The Hardware Podcast with Fexingo: Chips, Devices, and Electronics Engineering Conversations

In this episode of The Hardware Podcast with Fexingo, Lucas and Luna explore a surprising new frontier in chip design: embedding tiny accelerometers directly onto silicon. These micro-electromechanical systems, or MEMS, are typically separate components, but chipmakers are now integrating them into the die itself. The hosts discuss how STMicroelectronics and Bosch are leading the charge, with applications ranging from predictive maintenance in industrial motors to vibration-based energy harvesting for IoT sensors. They dive into the physics challenges—like isolating the fragile MEMS structure from the chip's own vibrations—and the manufacturing advances that make it feasible. By the end, you'll understand why on-chip accelerometers could be the next must-have feature in everything from automotive safety systems to wearable health monitors. Lucas and Luna also touch on the economics: integrating MEMS reduces bill-of-materials cost and improves reliability, but yields are still a hurdle. A focused, concrete look at a technology that's quietly reshaping the sensor landscape.

In this episode of The Hardware Podcast, Lucas and Luna explore how chip designers are integrating tiny transformers directly onto silicon to solve power delivery challenges. As processors demand lower voltages and higher currents, traditional voltage regulator modules are becoming a bottleneck. On-chip transformers, fabricated using standard CMOS processes, can step down voltages with minimal loss and switch at frequencies above 100 megahertz, enabling faster transient response and smaller external components. The hosts discuss a specific implementation from a recent International Solid-State Circuits Conference paper where researchers achieved 90 percent efficiency in a 12-volt-to-1-volt conversion using an integrated transformer with a magnetic core made from cobalt-zirconium-tantalum alloy.
