Flexible Capacitive Pressure Sensor with High Sensitivity and Wide Range Based on a Cheetah Leg Structure via 3D Printing
Flexible pressure sensors can be used in human–computer
interaction and wearable electronic devices, but one main challenge
is to fabricate capacitive sensors with a wide pressure range and
high sensitivity. Here, we designed a capacitive pressure sensor based
on a bionic cheetah leg microstructure, validated the benefits of
the bionic microstructure design, and optimized the structural feature
parameters using 3D printing technology. The pressure sensor inspired
by the cheetah leg shape has a high sensitivity (0.75 kPa–1), a wide linear sensing range (0–280 kPa), a fast response
time of roughly 80 ms, and outstanding durability (24,000 cycles).
Furthermore, the sensor can recognize a finger-operated mouse, monitor
human motion, and transmit Morse code information. This work demonstrates
that bionic capacitive pressure sensors hold considerable promise
for use in wearable devices
