Abstract

The invention discloses a flexible temperature sensor and a preparation process thereof. The sensor comprises flexible base materials located the topmost layer and bottommost layer of the sensor, sensor array lower electrodes located on the bottom-layer base material, a nano temperature sensitive material which is located on the lower electrodes and closely contacts with the lower electrodes, sensor array upper electrodes which are located on the nano temperature sensitive material and closely contact the nano temperature sensitive material, and an insulating layer material. According to the flexible temperature sensor and the preparation process thereof of the invention, the flexible temperature sensor can be prepared on a flexible base through a nano printing technology and can be applicable to temperature distribution monitoring of objects in different shapes. The flexible temperature sensor of the invention has the advantages of high flexibility, wide measurement range, stable performance, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a flexible temperature sensor realized by nano-printing technology and a preparation process thereof. Background technique [0002] Temperature sensors are widely used in both industrial and personal use. For example, various temperature sensing technologies such as thermal resistance, thermocouple, and optical fiber have been greatly developed in various fields. However, these temperature sensors are generally large in size, and it is difficult to install and arrange the temperature monitoring of small objects; moreover, the above-mentioned temperature sensors are made of non-flexible materials with high hardness, which cannot be applied to the surface of three-dimensional objects and used to measure three-dimensional objects surface temperature and distribution. [0003] Moreover, the above-mentioned sensors have defects such as limited service life and complex structure, so ...
