The invention discloses a sensor module based on a flexible substrate. The sensor module comprises a sensor part and an antenna part, wherein the sensor part and the antenna part use flexible insulating materials as substrates, and are connected through a lead or a clamp, the sensor part is used for sensing an external sensitive signal, the antenna part is used for transmitting and receiving a wireless signal, and the sensor part and the antenna part are combined for realizing detection and transmission of the external sensitive signal under the wireless condition. According to the sensor module, by using the flexible insulating materials such as PI and PET as the substrates and using various microelectronic microprocessing methods, the sensor part and a wireless emitting part are made on the substrates and are combined with the substrates together so that the novel sensor module which is passive, wireless and foldable, is high in portability, and is assembled is formed.
Description
technical field [0001] The invention relates to the technical field of detection and transmission of sensor signals, in particular to a sensor module based on a flexible substrate for detection and transmission of sensor signals. Background technique [0002] With the development of society and the improvement of people's living standards, it is becoming more and more urgent to detect light, small and bendable sensors in the fields of food safety, medicine and health. At the same time, with the development of the Internet of Things, the society has higher and higher requirements for wireless interconnection, and wireless sensors have attracted more and more attention. Sensors based on rigid substrates have been very mature, but their application scenarios are limited by the substrate itself and cannot meet market requirements. Therefore, flexible substrates have good development potential. [0003] Most of the current wireless transmission modules are made at one time based...
