Dual-Scale Porous Composite for Tactile Sensor with High Sensitivity over an Ultrawide Sensing Range
Publikováno v:
Small (Weinheim an der Bergstrasse, Germany). 18(39)
Porous structures have been utilized in tactile sensors to improve sensitivity owing to their excellent deformability. Recently, tactile sensors using porous structures have been used in practical applications, such as bio-signal monitoring. However,
