Abstract
To achieve a highly sensitive flexible piezoresistive sensor, an innovative strategy was developed by leveraging wrinkled structures and porous microstructures. Due to these specialized structures, the sensitivity can reach up to 1.58 kPa−1. Both macro and micro signal tests were conducted, revealing the ability to detect complex and weak signals found in human physiological responses. Importantly, due to its high sensitivity at low pressure, the sensor can differentiate the pulse rates of individuals, including children and adults. This highlights its potential as a wearable diagnostic device for real-time monitoring of human health under various conditions.
