Abstract
The invention relates to a flexible pressure sensing device based on carbon black dust-free paper and a manufacturing method thereof. The device comprises a pressure sensing part which comprises a plurality of carbon black-dust-free paper composite material layers, wherein the resistance of the pressure sensing part changes when the pressure sensing part is stressed; electrodes which comprise a first electrode and a second electrode, wherein the first electrode is connected with one surface of the pressure sensing part, and the second electrode is connected with the other surface of the pressure sensing part; a packaging layer which is used for packaging the pressure sensing part and the electrodes together; and a pressure detection part which is connected with the electrodes and detects the resistance of the pressure sensing part and determines the stress direction and / or the stress magnitude of the device according to the calculated resistance change. According to the flexible pressure sensing device based on the carbon black dust-free paper and the manufacturing method thereof, the device is simple in manufacturing process, low in cost, high in sensitivity, high in response speed, good in stability and wide in application range.
Description
technical field [0001] The present disclosure relates to the technical field of flexible electronics, in particular to a flexible pressure sensing device based on carbon black dust-free paper and a manufacturing method thereof. Background technique [0002] With the development of science and technology, flexible electronic devices have attracted widespread attention not only in technology but also in commercial applications. Flexible pressure sensors, as a type of device with skin-like functions, can be used in health monitoring, intelligent prosthetics, human-computer interaction First-class, due to the good flexibility of this type of pressure sensor, it can fit perfectly with the skin, and can monitor pressure-related human health parameters in real time; at the same time, it can also be used on robots or prosthetics to make its functions closer to function of the human body. However, in related technologies, the preparation of sensors is complex and costly, requiring c...
