TunnelSense | Dhairya J. Shah

IEEE RFID '24ACM/IEEE IPSN '24 Poster

TunnelSense turns a tunnel-diode oscillator into a sensor. Objects or people near the oscillator’s antenna shift its resonant frequency, and that shift is readable at a distance by a commodity receiver. This gives non-contact sensing of presence, motion and material changes at power levels comparable to backscatter tags, without a separate sensing front-end or microcontroller in the loop.

The approach was published at IEEE RFID 2024 and presented as a poster at IPSN ‘24.
