Ultra-low-power Wireless Ring Mouse
This paper addresses the short battery lifespan of wireless mouse rings by introducing picoRing mouse. We develop a near-field sensitive inductive telemetry, which allows a ring coil to send its data to nearby wristband coil in ultra-low-power way. This approach drastically extends the ring’s operation time from a few hours to over 200 hours on a 27 mAh battery.
