Abstract
Flexible pressure sensors have drawn substantial community interest as a result of the advancement of contemporary technology. Inspired by the unique sensory organs of crocodiles, an ordered bionic dome-shaped fold structure array was prepared using a facile process in this paper, and electrical experiments confirmed the enhancement of the capabilities of piezoresistive flexible pressure sensors. The results revealed that this type of flexible pressure sensor presented a sensitivity of 8.87 kPa−1, could withstand a maximum pressure of 60 kPa, a minimum detection pressure of 10 Pa, a response time of 70 ms, and maintained stable performance under 5000 repeated presses. In addition, the flexible pressure sensors based on dome-shaped fold structure arrays have been successfully applied for human signal detection and plantar pressure monitoring system. The current research has significant implications for the manufacturing and practical applications of highly effective flexible pressure sensors.
