Jinwoo Sim

Jinwoo Sim is a graduate student in electrical engineering and computer science, expanding knowledge on nanoscale energy harvesting. His work focuses on developing quantum-material-based rectifiers that convert ambient gigahertz and terahertz radiation—emitted by wireless networks and the atmosphere—into usable electrical power. These next-generation devices, based on the nonlinear Hall effect in topological materials, eliminate the frequency limits and threshold losses that constrain traditional diodes. As a MathWorks Fellow, Jinwoo will develop a fully integrated energy harvesting system that combines quantum-enabled rectifiers with impedance-matched antennas and power management circuits. MATLAB plays a critical role across Jinwoo’s workflow, enabling automation of complex multi-instrument measurements, real-time diagnostics, and high-throughput data analysis. He has also developed reusable MATLAB toolkits for experimental control and circuit modeling, which he plans to share publicly. His work could lead to self-powered sensors, wearables, and electronics, helping to realize a scalable, battery-free future for connected devices.
