Abstract

The invention discloses a sensor, a system, a pressure detection circuit, a method and an electronic skin. By using a photosensitive element to sense light and output an optical signal, such as voltage, it provides at least a new pressure detection device compared with the existing mechanical pressure detection device The pressure detection method, and the sensor can be applied to precision equipment such as circuits, with high accuracy, or as an alarm device, with high alarm sensitivity, and can also be set to multi-layer alarm, which expands the application scenarios of the sensor.

Description

technical field [0001] The invention relates to the technical field of pressure sensing. More specifically, it relates to sensors, systems, pressure detection circuits, methods and electronic skins. Background technique [0002] The existing mechanical process technology and micro-electro-mechanical system process of pressure sensors are complex, the back-end process equipment is expensive, and the process accuracy is high, resulting in low production capacity, poor quality control, and high production costs. [0003] Human skin has structures such as villi and nerve endings, and has functions such as sensing force, sensing temperature, and sensing pain. However, when the superficial skin is damaged, or the extremities are damaged, etc., it may cause sensory impairment. Especially for patients who use prosthetics, it is difficult to restore the original tactile sensation of fingers and other objects through prosthetics. [0004] In order to overcome at least one of the ex...
