摘要： A triboelectric nanogenerator-based pressure sensor may be deployed on a wearable device to monitor a pulse fluctuation, or may be deployed on an electronic device having a touchscreen to detect a touch action. The sensor includes: two friction layers (301, 302) and at least one electrode layer (303, 304). The two friction layers (301, 302) are respectively made of materials with different electron gain and loss capabilities, and a surface of at least one friction layer (301, 302) includes a multi-level micro-nano structure, so that when there is pressure, equal-quantity and opposite net charges corresponding to the applied pressure are induced on the two friction layers (301, 302). The multi-level micro-nano structure includes micro-nano columnar structures with at least two different heights. The electrode layer (303, 304) is configured to generate a current based on the net charges. The multi-level structure with different heights is designed, so that the pressure sensor can also maintain high sensitivity to a large static force, and a measurement range of the pressure sensor can be extended. In this way, the sensor maintains same or similar sensitivity to all static forces.
