Large‐Area Piezoresistive Tactile Sensor Developed by Training a Super‐Simple Single‐Layer Carbon Nanotube‐Dispersed Polydimethylsiloxane Pad

Piezoresistive Tactile Sensors A high-precision tactile sensor is not achieved by means of complexly processed devices, but by training simple bulk materials. A crude carbon nanotube-dispersed polydimethylsiloxane pad—with a bias applied to the center and the resultant piezoresistive current detected at several electrodes located on the pad edge—plays a smart sensory role without the need for complicated fabrication of micro-engineered structures.
