Field‐Driven Activation of Solid‐State Devices in Open Circuits for Energy Harvesting and Wireless Sensing

∝1/r, validated experimentally on both linear and non-linear components. The resulting field-driven activation enables energy harvesting in open circuits, multi-channel control, and wireless sensing of human motion and mechanical vibrations over meter-scale distances. This quasi-static capacitive coupling operates in a distinct regime compared to resonant wireless power transfer, because it is drive by low-frequency, motion induced electric field changes that generate transient displacement currents in floating circuits. The findings here enable contact-free activation of electronic components through discrete energy transfer rather than traditional continuous power delivery.
