Self-Spiking Linear Neuromorphic Soft Pressure Sensor for Underwater Sensing Applications. [PDF]

Adv Mater
This study presents a novel design of a neuromorphic pressure sensor that can generate self‐spiking symmetric signals with direct event‐based encoding through the integration of magnetic spheres and alternating coil circuits. The key advantages of this work include high linearity up to 200 kPa (R2 = 0.997), self‐spiking behavior for simplified signal ...
