Flexible integrated sensor and method for simultaneously measuring temperature, pressure and medium

Abstract

The invention discloses a flexible integrated sensor and a method for simultaneously measuring the temperature, pressure and medium. The flexible integrated sensor comprises a circuit board and a pressure sensitive material, the circuit board is a double-sided board, one surface of the circuit board is provided with a temperature sensor and a material identification sensor, and the other surface of the circuit board is provided with an interdigital electrode; and in the using process, the temperature sensor and the material recognition sensor make contact with an object to be measured, the pressure sensitive material makes contact with the interdigital electrode, and the pressure sensitive material and the interdigital electrode form a force sensor. According to the flexible integrated sensor, measurement of various physical quantities can be completed through the same sensor, so that the types and the number of used sensors are reduced, the cost is reduced, and the flexible integrated sensor is simple in structure, small in number of components, small in device size and suitable for various measurement environments.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a flexible integrated sensor and a method for simultaneously measuring temperature, pressure and media. Background technique [0002] Sensor technology is an important means for human beings to obtain external information. Together with computer technology and communication, it is called the three pillars of information technology. The sensor can sense the specified measured object and convert it into a usable signal according to certain rules, which is a necessary part of the system to perceive the external environment. [0003] The temperature of an object is an important physical quantity that represents the degree of coldness or heat of an object. The higher the temperature, the hotter the object. Force can deform objects, and it is often necessary to measure the magnitude of force in production and life. Dielectric constant, also known as permittivity or relative permittiv...
