Problems solved by technology

[0003] At present, most thermal resistance temperature sensors are made of metal. The most commonly used thermal resistances are platinum thermal resistance and copper thermal resistance. However, these sensors are made of non-flexible materials and can only measure the temperature of objects with flat surfaces. Poor compatibility and requires additional sensor packaging
In addition, the flexible temperature sensor in the related art also has the disadvantages of complicated fabrication and low detection sensitivity.

Abstract

The invention discloses a flexible temperature sensor, a manufacturing method thereof and a flexible device. The flexible temperature sensor comprises: a flexible substrate on which electrodes are arranged; a mixed liquid which is arranged on the flexible substrate and contacts the electrodes; The liquid includes ionic liquid and porous conductive black particle material; the protective plate is arranged on the side of the flexible substrate where the mixed liquid is provided to protect the mixed liquid. According to the flexible temperature sensor of the present invention, by providing a mixed liquid of ionic liquid and porous conductive black particle material on the flexible substrate, it is convenient to make the flexible temperature sensor, and it is beneficial to realize accurate temperature detection. The mixed liquid is used as a fluid, and its The fluidity guarantees the continuity in a certain area and will not break when stretched and bent, so it can be used in the design of flexible devices.

Description

technical field [0001] The present invention relates to the technical field of sensors, in particular to a flexible temperature sensor, a method for manufacturing the flexible temperature sensor, and a flexible device provided with the flexible temperature sensor. Background technique [0002] In related technologies, with the increasing popularity of the concept of the Internet of Things, the sensor market once again ushers in rapid development opportunities. As an important category of sensors, temperature sensors account for more than 15% of the total demand for sensors, so the market for temperature sensors is broad. Thermal resistance temperature sensor is a commonly used temperature sensor product, which can measure temperature by using the principle that the resistance value of a conductor or semiconductor changes with temperature. It has the advantages of stable performance, flexible use, and high reliability. [0003] At present, most thermal resistance temperature...
