Description

technical field [0001] The invention relates to the field of imaging technology, in particular to the field of pressure imaging, and specifically refers to a sensor that uses a MEMS pressure sensor array to form pressure imaging pixels, and obtains image information of a pressured object by collecting data from the pressure imaging sensor. Background technique [0002] With the continuous development of MEMS sensor technology, the original bulky sensors can be made very small, which is very convenient to form sensors into arrays, so as to realize the functions and technological breakthroughs that could not be realized before. At present, imaging technologies are mainly wave imaging technologies, such as visible light waves, infrared light waves, ultrasonic waves, and radar electromagnetic waves. The above-mentioned wave imaging technology has a large amount of information and reflects the information of the imaged object more comprehensively. But at the same time, due to th...
