You might think that a smart watch or fitness wearable would not be a thermal concern for users. After all, they only have small rechargeable batteries and sip that battery’s energy to extend operating time as much as possible, typically at least 24 hours.

Their heat dissipation is many orders of magnitude less than that of a CPU, GPU, or other processor-core device cooking along at tens and even hundreds of watts. Nonetheless, wearables can be highly localized sources of heat and therefore cause potential skin problems.

I hadn’t thought about the extent of this localized heating on skin due to wearables until I coincidentally saw several items on the subject. The first was an IEEE conference article re- posted at InCompliance magazine, “Reduced-Order Modeling of Pennes’ Bioheat Equation for Thermal Dose Analysis.” The second was an article in Electronics Cooling, “Thermal Management and Safety Regulation of Smart Watches.”

The first paper was intensely analytic with complicated thermal models and equations, and while I didn’t want to go through it in detail, I did get the overall message: you can get surprisingly high localized skin heating from a wearable.

It pointed out that the simple term “skin” actually comprises four distinct tissue layers, and each is unique in its geometric, thermal, and physiological properties. The outermost layer is the exposed epidermis, beneath it is the dermis which is the “core” of the skin, then the subcutaneous fat (hyodermis) layer, and finally, the inner tissue muscle and bone, Figure 1.

Figure 1 The term “skin” really refers to a four-layer structure, where each layer has distinctive material, thermal, and other properties, most of which are hard to measure. Source: Cleveland Clinic

Damage to the skin is analyzed by the extent of partial or complete necrosis (death) of each layer. While that’s more than I wanted to know, I was curious about the assessment of skin damage.

It turns out that there is, as expected, a quantitative assessment of thermally induced damage and it is based on cumulative exposure at various temperatures. This thermal dose is estimated as cumulative equivalent minutes at 43°C, or CEM43°C, which provides a time and duration number:

Where T is tissue temperature, t is time, and R is a piecewise-constant function of temperature with:

 R(T) = 0.25 for T ≤ 43°C and = 0.5 for T > 43°C.

So far, so good. The rest the of lengthy paper delved into models of heat flow, heat spreading through the skin, transforming surface data into three-dimensional data, and more. The analysis was complicated by the fact that heat flow through the layers is hard to measure and model, especially as the skin layers are anisotropic (the flow is different along different axes).

Cut to the chase: even a modest self-heating of the wearable can cause skin damage over time, and so must be modeled, measured, and assessed. How much heating is allowed? There are standards for that, of course, such as IEC Guide 117:2010, “Electrotechnical equipment – Temperatures of touchable hot surfaces.”

What to do?

Knowing there’s a problem is the first step to solving it. In the case of wearables, the obvious solution is to reduce dissipation even further, which would also increase run time as an added benefit. But efforts are underway to go beyond that obvious approach.

Coincident with seeing the two cited articles, I came across an article in the scholarly journal Science Advances, “Ultrathin, soft, radiative cooling interfaces for advanced thermal management in skin electronics.” A research team led by City University of Hong Kong has devised a photonic, material-based, ultrathin, soft, radiative-cooling interface (USRI) that greatly enhances heat dissipation in devices.

Their multifunctional composite polymer coating offers both radiative and non-radiative cooling capacity without using electricity and with advances in wearability and stretchability. The cooling interface coating is composed of hollow silicon dioxide (SiO2) microspheres for improving infrared radiation along with titanium dioxide (TiO2) nanoparticles and fluorescent pigments, for enhancing solar reflection. It is less than a millimeter thick, lightweight (about 1.27g/cm2), and has robust mechanical flexibility, Figure 2.

When heat is generated in a wearable fitted with this thermal interface, it flows to the cooling interface layer and dissipates to the ambient environment through both thermal radiation and air convection. The open space above the interface layer provides a cooler heat sink and an additional thermal exchange channel.

To assess its cooling capacity, they conformally coated the cooling interface layer onto a metallic resistance wire functioning as a heat source, Figure 3. With a coating thickness of 75 μm, the temperature of the wire dropped from 140.5°C to 101.3°C, compared with uncoated wire at an input current of 0.5 A with a 600-μm thickness, it dropped to 84.2°C for a temperature drop of more than 56°C. That’s fairly impressive, for sure.

Infineon Technologies AG introduces the SSO10T TSC package with OptiMOS MOSFET technology. With its direct top-side cooling concept, the package offers excellent thermal performance. This eliminates heat transfer into or through the PCB of the automotive electronic control unit. The package enables a simple and compact double-sided PCB design and minimizes cooling requirements and system costs for future automotive power designs. The SSO10T TSC is therefore well suited for applications such as electric power steering (EPS), EMB, power distribution, brushless DC drives (BLDC), safety switches, reverse battery, and DCDC converters.

The SSO10T TSC has a 5 x 7 mm² footprint and is based on the established industry standard SSO8, a 5 x 6 mm² robust housing. However, due to its top-side cooling, the SSO10 TSC offers more than 20 percent and up to 50 percent higher performance than the standard SSO8 – depending on the thermal interface (TIM) material used and the TIM thickness. The SSO10T TSC package is JEDEC listed for open market and provides wide second source compatibility. As a result, the package can be introduced quickly and easily as the future standard for top-side cooling.

The SSO10T package enables a very compact PCB design and reduces the system footprint. It also lowers the cost of the cooling design by eliminating vias, resulting in lower overall system costs and design effort. At the same time, the housing offers high power density and efficiency, thus supporting the development of future-proof and sustainable vehicles.

The first 40 V automotive MOSFET products with SSO10T are now available: IAUCN04S6N007T, IAUCN04S6N009T, IAUCN04S6N013T, IAUCN04S6N017T. Further information is available at https://www.infineon.com/cms/en/product/promopages/SSO10T/.

Embedded systems are the foundation of today’s electronic devices, spanning sectors as diverse as consumer electronics, telecommunications, industrial, medical, automotive and aerospace applications. Ensuring seamless operation is critical, which means that engineers encounter complex challenges as they design increasingly compact embedded systems and align them with today’s requirements for efficiency, safety, reliability and interoperability. Rohde & Schwarz offers comprehensive test and measurement solutions to meet these challenges and will present its highlights at the embedded world Exhibition & Conference 2024 in Nuremberg, Germany.

Rohde & Schwarz is showcasing its state-of-the-art test and measurement solutions tailored to the embedded industry at the embedded world Exhibition & Conference. At the company’s booth 4-218 in hall 4 of the Nuremberg Exhibition Center, visitors will have the opportunity to gain insights into embedded design testing, including testing of digital designs and interfaces, power electronics, electromagnetic compatibility, wireless connectivity and in-vehicle networks.

One-box test solution supports new Bluetooth® Low Energy test features

One highlight will be the R&S CMW wideband radio communication test platform (R&S CMW500, R&S CMW270) covering the new Low Energy (LE) feature Bluetooth Channel Sounding (CS). CS extends the positioning capabilities of low energy devices based on high accuracy distance measurements. The R&S CMW platform offers fully featured RFPHY test capabilities using the phase-based ranging (PBR) principle. High-performance internal signal generators and analyzers allow repeatable high-quality device verification.

The R&S CMW platform also supports Bluetooth® Low Energy over-the-air (OTA) receiver and transmitter measurements, as defined in the upcoming Unified Test Protocol (UTP) test mode. The OTA test capability allows easy RFPHY testing of devices that do not have a physical test connector. The new Bluetooth core specification defining the CS and UTP modes is expected to be released later this year.

The R&S CMW platform is a comprehensive, fully automated test solution for verifying the physical layer functions Bluetooth Low Energy and Bluetooth Classic with the addition of LE audio measurements. Visitors can experience the new LE test modes live at the Rohde & Schwarz booth.

Another highlight is the MXO 5 oscilloscope from Rohde & Schwarz, the world’s first eight-channel oscilloscope that can detect 4.5 million acquisitions and a total of 18 million waveforms per second across multiple channels. The MXO 5 shows more of a signal’s activity than any other oscilloscope in both the time and frequency domains. With a simultaneous acquisition memory of 500 Mpoints across all eight channels, it offers twice the standard memory of competitive models. As the first eight-channel oscilloscope with digital triggering, it sets a new standard for signal analysis. It is also the first oscilloscope to offer 45 000 FFTs per second. Visitors to the Rohde & Schwarz booth will have the opportunity to see this innovative instrument in action, testing system-on-chip (SoC) power designs with multiphase buck converters.

High-speed digital interfaces play a pivotal role in electronic designs. Increasing data rates and integration densities are a challenge for designs at the IC, board and system levels. Visitors to the show can learn about powerful tools for system verification and debug, as well as compliance testing for signal integrity in interfaces, PCBs and interconnects, directly from experts in the field. Demo setups at the Rohde & Schwarz booth include USB 3.2 signal integrity debugging with receiver equalization emulation and advanced eye diagram analysis with the R&S RTP164B oscilloscope, as well as protocol decoding with the MXO 4 oscilloscope.

In addition, visitors will find a solution for fully automated (pre-)compliance testing and verification of high-speed cables (IEEE 802.3bj/by/cd/ck and PCIe 5.0/6.0) using the R&S ZNrun automation test suite, an R&S ZNA or R&S ZNB vector network analyzer and the R&S OSP320 open switch and control platform. The multiport physical layer analysis of a PCIe 6.0 compliant cable is performed by accurately de-embedding the signal with the R&S ZNB43 vector signal analyzer.

The new Wi-Fi 7 standard supports up to 16×16 MIMO with 320 MHz wide channels and 4096 QAM modulation, providing extremely fast and stable connections. When developing Wi-Fi 7 devices, the RF TX and RX characteristics must be measured under real-world conditions in signaling mode. The R&S CMX500 multi-technology multi-channel signaling tester is now available with integrated Wi-Fi 7 test functions. Test environments with multiple RF chains are particularly important in Wi-Fi 7, where multilink operation (MLO) is a key feature. The tester’s flexibility, support for multiple radio technologies and embedded IP test capabilities make it a versatile solution for a wide range of Wi-Fi 7-specific tests, such as 2×2 MIMO, 6 GHz band with out-of-band discovery, coexistence and E2E test capabilities.

Accurate ranging, low power consumption, high security and reliability – these are the features of ultra-wideband (UWB) technology features that make it suitable for many secure ranging applications, especially as a digital key. At embedded world 2024, Rohde & Schwarz will present the R&S CMP200 radio communication tester with integrated UWB test capabilities for solving UWB test challenges in mass production as well as in R&D.

Because all electronic controllers are susceptible to conducted or radiated electromagnetic emissions, many finished electronic products fail their first EMC compliance test. Every day spent debugging, isolating and correcting the EMI problem increases the time to market. As a leader in EMC testing, Rohde & Schwarz will present solutions that integrate EMI testing into the product design process. Visitors can learn how to use the powerful R&S RTO6 oscilloscope for EMI debugging or the R&S FPL1000 signal and spectrum analyzer for EMC pre-compliance testing.

Rohde & Schwarz offers the R&S ESW EMI test receiver for final EMC compliance tests. With the new R&S ESW-B1000 wideband option, the R&S ESW can expand its FFT bandwidth to up to 970 MHz to measure the complete CISPR frequency Bands C and D in a single operation. The wide bandwidth helps to intercept sporadic interference and enables higher reliability and repeatability in commercial and MIL-STD tests. The extremely high measurement speed opens up new possibilities for compliance testing as well as for emissions analysis and debugging. The R&S EPL1000 EMI test receiver offers fast, accurate and reliable EMI compliance measurements up to 30 MHz at a competitive price in the full CISPR 16-1-1 compliance receiver class for both device developers and conformance test houses.

Battery life is usually one of the most important specifications for battery-powered devices. Visitors can explore the R&S NGM200 high-precision DC power supply in a battery testing and simulation setup. The application software facilitates battery discharging, as well as the repeated discharge and recharge of rechargeable batteries. Continuous monitoring and recording of open circuit voltage and voltage under load are integral features. The DC power supply can be remotely controlled from a PC with the application software installed.

Another test setup allows visitors to use various smartwatch apps to observe how GPS affects power consumption in real time. A new analysis tool helps developers analyze power consumption data collected with the R&S NGU power supply. These source measure units can be used for battery modeling and simulation. They measure the current consumption of battery-powered devices in all phases and during the transition from sleep to active mode, which is important for design engineers.

Rohde & Schwarz will present its R&S FSPN high-speed phase noise analyzer up to 50 GHz in a demonstration test setup with a VCO device under test. Equipped with two low phase noise synthesizers and a real-time cross-correlation engine for increased measurement sensitivity, it is ideal for characterizing sensitive synthesizers and oscillators in R&D. In addition, Rohde & Schwarz will showcase its R&S LCX200 LCR meters with customized impedance measurement functions that are suitable for all discrete passive components up to 10 MHz. Using the R&S LCX sweep software tool, they can even per­form sweep measurements displaying numerous charts. The MFIA impedance analyzer from Zurich Instruments AG (a subsidiary since 2021) will also be on display. The MFIA provides impedance analysis for both low and high impedance components and has a measurement mode for quickly tracking impedance changes in devices under test.

These and other test solutions can be found at the Rohde & Schwarz booth 4-218 in hall 4 at the embedded world Exhibition & Conference from April 9 to 11, 2024 in Nuremberg, Germany. For more information visit: www.rohde-schwarz.com/embedded-world
