As cities move toward electric mobility and smarter infrastructure, seamless and safe power delivery is more important than ever. Shivam Rajput, Founder and CEO of ElectraWireless, is pioneering wireless electricity solutions that reduce EV downtime, extend fleet lifecycles, and power devices without cords or plugs. Combining advanced materials science, adaptive resonant coupling, and smart thermal management, his innovations aim to make wireless power scalable, safe, and efficient. In this conversation with ELE Times, he shares lessons from pilots, technological breakthroughs, and how India could benefit from cost-effective, large-scale wireless EV infrastructure.

Excerpts:

ELE Times:  What implications does wireless electricity have for EV adoption, safety, and the broader global energy transition?

Shivam Rajput: Wireless electricity isn’t just about convenience, it addresses real consumer challenges and can help the EV market thrive. EV adoption today is often slowed by downtime, manual charging, connector wear, and safety concerns. Consumers want simple, safe, and sustainable solutions, not just car features. Wireless electricity ensures EVs charge automatically at parking spots or even while moving, maintaining battery health and keeping vehicles ready at all times. Beyond EVs, homes, workplaces, and cities become safer with fewer exposed wires and connectors, reducing the risk of accidents and outages. This technology also minimizes energy waste, making it a crucial step in the global energy transition.

ELE Times: What are the key breakthroughs that have enabled high-power wireless electricity transmission through everyday surfaces like wood, quartz, or automotive-grade materials?

Shivam Rajput: Our system delivers power only when needed, without heating surfaces or wasting energy. Materials innovation allows seamless integration into wood, quartz, automotive-grade panels, and other common surfaces. Safety is ensured through foreign object detection, which automatically halts transmission if anything interferes. For autonomous systems, from robotics to EVs, devices no longer need to stop to plug in; they charge automatically wherever transmitters are installed. These breakthroughs make high-power wireless electricity scalable, safe, and efficient across multiple sectors.

ELE Times:  What lessons emerged from pilots in robotics, kitchens, and workplace environments, and how are they shaping your approach to scaling the technology?

Shivam Rajput: Pilots highlighted three critical lessons: seamless integration, safety, and efficiency. In smart kitchens, multiple appliances operated wirelessly without interference, showing the importance of modular design. Workspaces benefited from embedded, unobtrusive power, improving usability and safety. In robotics and autonomous systems, wireless charging dramatically reduced downtime, enabling continuous operation and boosting productivity. Eliminating manual plug-ins also reduces electrical faults, making devices safer for children and workplaces. These insights inform a scalable platform ready for enterprise-level and consumer applications.

ELE Times:  In what ways could wireless charging reduce downtime and extend the lifecycle of EV fleets?

Shivam Rajput: Wireless charging allows EVs to charge in motion or at strategically located parking spots, reducing wear on connectors and preserving battery health. Fleets can operate longer, with fewer interruptions, while maintenance costs decrease. This contactless approach accelerates operations and reduces total cost of ownership, making EV fleet management more efficient and sustainable.

ELE Times:  Can wireless power assist in building scalable, cost-effective EV infrastructure in countries such as India?

Shivam Rajput: India is one of the most promising markets for EV adoption. Our retrofit-friendly wireless system integrates with existing grids, lowering installation complexity and costs. By embedding chargers into roads, parking spots, or city infrastructure, EVs can charge seamlessly while driving or parked, what we call “monorail charging.” This approach enables large-scale adoption, ensures reliability, and reduces safety risks associated with exposed connectors. The system supports faster EV market growth while building a sustainable, energy-efficient infrastructure.

ELE Times: What technological advances from ElectraWireless enabled them to scale the transmission of wireless power from as low as 5W all the way up to 40kW?

Shivam Rajput: Adaptive resonant coupling, dynamic field shaping, and smart thermal management allow safe and efficient power delivery across surfaces, from small electronics to EVs. Foreign object detection ensures absolute safety during transmission. Precision energy delivery reduces waste and maintains high efficiency for continuous operation. These advances unlock a fully scalable wireless electricity ecosystem, enabling applications in robotics, kitchens, workspaces, and urban EV infrastructure.

Satellites, spacecraft, and defense systems rely on increasingly complex software ecosystems that integrate open-source, third-party, and legacy components. Recent cybersecurity events have highlighted how vital it is to track, secure, and manage these software supply chains.

The Risk of Vulnerable Third-Party Components

At Black Hat 2025, some very serious vulnerabilities were discovered in some of the most commonly used platforms for satellite control: Yamcs, OpenC3 Cosmos, and NASA’s cFS Aquila. Such flaws-range from remote code execution, denial of service, weak encryption to manipulation of satellite operations-force criminals into changing orbital paths or stealing cryptographic keys, usually without even detection.

Even seeming-to-be-secure encryption libraries such as CryptoLib-which NASA uses-were found to harbor multiple critical vulnerabilities. Exploiting these, attackers could crash the onboard software, reset its security state, or compromise encrypted communications. These findings reinforce that third-party components remain among the easiest risks to exploit in aerospace and defense software.

SBOMs: Ensuring Transparency Across the Software Stack

Software Bill of Materials lists all components within a system involved. In practice, it finds vulnerabilities, manages risk, considers compliance, and goes into incident response. The SBOM can be only as good as its accuracy, completeness, or governance structure.

In other words, to improve security posture, an organization must hold centralized processes for the validation, enrichment, and continuous surveillance of SBOMs, so that both upstream ones (those from development) and downstream ones (those from deployed systems) are held accountable, validated, and acted upon.

Closing the Gaps

Modern SBOM platforms, such as Keysight’s solutions, enhance binary similarity checks and code emulation to detect components when source information is partial or missing. This allows SBOMs to be reliably created for firmware and software or for container images so that no single component-in whatever form it exists-goes untracked.

Hence, giving full visibility, rigorous validation, and operational governance serve systems in aerospace and defense better in recognizing vulnerabilities, quick incident response, and establishing trust across software supply chains. This closes critical gaps while trying to keep mission-critical systems safe from the ever-evolving cyber threats.

Electrochemical impedance spectroscopy (EIS) is a powerful technique for studying electrochemical systems such as electrochemical cells, batteries, fuel cells, corrosion protection setups, and sensors. By differentiating processes such as charge transfer across the electrode interface, diffusion, double-layer behavior, etc., by applying small sinusoidal signals generated in random magnitudes over a wide frequency range, we invoke responses from such mechanisms. Equivalent circuits in the traditional sense can conveniently give impedance data representations; however, they do not suffice when overlapping or nonideal processes come into play. Modern physics-based modeling approaches enable the researcher to consider adsorption, mass transport, and electrode surface effects far beyond simple resistor–capacitor analogies.

EIS Real-Life Applications

Sensitivity renders EIS paramount for:

Batteries: Detects ion and electron transport at early stages of degradation and capacity fading.

Corrosion: Detects subtle interface changes between metal and electrolyte in pipelines, concrete, and marine structures.

Fuel Cells: Performance and durability improvements by separating contributions of catalyst layers, membranes, and reactant flows.

Sensors: Evaluates electrode interactions with target molecules, enabling applications like glucose monitoring.

The Limitations of Equivalent Circuits

For the simpler reactions, the impedance data frequently fit an elementary equivalent circuit: a resistor in series with a parallel resistor-capacitor pair. In a Nyquist plot, this will look like a neat semicircle corresponding to charge transfer resistance. However, rarely do real systems behave so nicely. Adsorption, diffusion, and electrode morphology will add time constants and overlapping processes with which the equivalent circuit cannot always keep up. Physics-based models are, therefore, chosen to solve the underlying electrochemical equations, thus providing a more accurate picture of how these processes may interrelate.

Consider the Nonidealities of EIS:

Important Factors

1. Adsorption–Desorption Dynamics

Intermediates may adsorb on electrodes during electrochemical reactions. The changing surface coverage may, over time, change the impedance response. For instance, with copper deposition, a progressive increase in coverage of additives changes the spectra from two capacitive loops into one dominated by an inductive loop at low frequency. Such effects demonstrate the crucial nature of adsorption in the design of such systems.

2. Mass Transport Limitations

In fuel cells, the diffusion and convection of gases such as hydrogen and oxygen significantly affect performance. Through impedance plots, one can observe the changes in charge-transfer and diffusion contributions as functions of the operating potential:

• Distinct high- and low-frequency loops at intermediate voltages
• At low voltages, loops combine with overlapping time constants
• On the strongly cathodic side, diffusion is dominant, and a single huge loop appears

This sequence clearly demonstrates the ability of EIS to differentiate between reaction kinetics and transport limitations.

3. Electrode Surface Effects

Surface roughness and uneven geometries alter the effective electrochemical area, thus shifting the impedance response. Accounting for electrode structures helps render better predictions in situations where morphology is important.

Handling Residual Behaviors

Sometimes, the impedance response cannot be explained by referring to adsorption, diffusion, or surface structure. A constant phase element (CPE) is then introduced to incorporate frequency-dependent effects that deviate from an ideal capacitive behavior. From a mechanistic standpoint, (CPE)behave as systems in which the mathematical expression describing a single mechanism can be modified with a continuous parameter that accounts for system complexity.

Conclusion:

Electrochemical impedance spectroscopy has remained one of the most versatile electrochemical experimental probes, and by moving beyond the simple circuit analogy to include adsorption, diffusion limitation, and surface-effects, researchers gained a more realistic view of the system behavior. Modeling platforms such as COMSOL Multiphysics support these newer approaches, albeit all electrochemical disciplines offer a general foundation.

From extending battery lifetimes to detecting early corrosion, EIS when paired with detailed physical insights continues to unlock new possibilities for innovation and reliability in electrochemical technologies.

I got this UniFi AP-AC-HD from my school to try and repair. My teacher said he dropped it when renovating one of the classrooms. But sadly, it seems like the SOC got damaged. Spent a long time trying to debug it. PoE buck converter works, all voltages correct, but no CPU Activity whatsoever. Not even a clock signal on the flash chip. But hey, here we have its guts!!
