Description
technical field [0001] The invention relates to the field of sensors, in particular to a pressure sensor. Background technique [0002] With the rapid development of science and technology, intelligent portable electronic devices have gradually become popular, such as smart phones, smart bracelets, smart hands, tablet computers and so on. While users are constantly pursuing the intelligence of portable electronic devices, they pay more attention to the need for portable electronic devices to have a rich and colorful user experience. At present, more and more manufacturers place pressure sensors in portable electronic devices. The air hole design of the existing pressure sensor is relatively large, which easily causes pollution to the inside of the pressure sensor and affects the performance of the pressure sensor. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a pressure sensor, which has the characteristics o...
