Abstract
The invention provides a high-stability anti-electromagnetic-interference bionic flexible strain gauge and a preparation method thereof. The high-stability anti-electromagnetic-interference bionic flexible strain gauge comprises an upper packaging layer, a crack function structure layer and a lower packaging layer which are sequentially arranged from top to bottom, wherein the crack function structure layer is a flexible carbon-based composite film with a plurality of cracks, a photoelectric detector is embedded in the upper packaging layer, and a light-emitting diode (LED) is embedded in thelower packaging layer. The bionic flexible strain gauge comprises the upper packaging layer embedded with the photoelectric detector, the lower packaging layer embedded with an LED and crack functionstructure layer embedded with a plurality of cracks, an optical signal is used as a feedback quantity, the measurement of an external tiny strain signal can be realized, the stability and reliabilityare high, the response time is short, and the strain real-time monitoring and visualization are realized.
Description
technical field [0001] The invention relates to the technical field of flexible sensors, in particular to a bionic flexible strainer with high stability and anti-electromagnetic interference and a preparation method thereof. Background technique [0002] In recent years, with the popularization and wide application of the mobile Internet, people's demand for consumer electronics products continues to expand. Driven by the joint efforts of technology, users, and industries, the sensor components in smart wearable devices need to be closer to people's lives, fully realizing the data connection and intelligent feedback between people and devices. [0003] Traditional strain sensors are usually based on strain-electricity, with electrical signals as the carrier for external stimulus conversion and transmission, and wires as the medium for transmitting electrical signals. Therefore, the strain sensor is easily affected by the electromagnetic field and working conditions when use...
