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