Description

technical field

[0001] The present disclosure relates to the technical field of semiconductors, in particular to a flexible sensor and a flexible signal detection device. Background technique

[0002] The structure of the sensor can usually be divided into signal sensing layer, signal conversion layer and signal transmission layer. The signal sensing layer responds to the signal to be measured by the sensor through processes such as structure and electrochemical reactions; the function of the signal conversion layer is to convert different measurement response signals into electrical signals that can be measured by the circuit. With the development of science and technology, people often need to use different types of sensors in the process of using electronic devices to measure human body signals. Sensors can be divided into mechanical, electrical, thermal, optical, magnetic and other types according to different measurement signals. Different sensors have different measur...
