Organic pressure sensor and its use method

Abstract

This invention belongs to the area of sensor technology; concretely it is an organic pressure transmitter and the application method. This sensor's sensitive material adopts the organic material, including the organic conjugate small member semi conducting material, the small molecular material adulterant and so on. This pressure transmitter is sensible, its volume is small, the weight is light, the cost is low, and especially suitable to make the curving pressure transmitter array. This invention may be used in robot's pressure sensation, the sense of touch as well as in the industry automatic control relates to pressure transmitter and the array, the application prospect is broad.

Description

technical field

[0001] The invention belongs to the technical field of sensors, and in particular relates to a pressure sensor using an organic conjugated small molecule semiconductor material as a sensitive material and a use method thereof. Background technique

[0002] At present, the commonly used pressure sensors include strain gauge pressure sensors, ceramic pressure sensors, diffused silicon pressure sensors, piezoelectric pressure sensors, and semiconductor (mainly silicon) pressure sensors, etc. There are also conductive rubber pressure sensor elements doped with graphite particles. Most of these components are relatively large in size and heavy in weight, and the pressure sensing components cannot be further miniaturized, and it is difficult to form a large array of micro components, and its rigid device structure also prevents the device from being bent. It is not easy to form a "tactile" measurement condition.
