A novel electronic PS pressure sensor 1

PS pressure sensor is an electronic pressure sensor made of semiconductor diaphragm structure, which can convert the physical quantity of air pressure into electrical signals and detect pressure changes with high accuracy and linearity. It is a new product launched by Panasonic Corporation in recent years.diode

As early as 1954, C.S. Smith in the United States first confirmed the semiconductor piezoelectric resistance effect. In 1955, C. Herring pointed out that this piezoelectric resistance effect is a phenomenon caused by the action of stress, resulting in changes in the energy states of conductors and valence electron bands, as well as changes in the number and mobility of charge carriers. Japan began research and development in 1970, first applied to blood pressure monitors, and later widely used in the field of process control and car engine control. In recent years, electronic pressure sensors have been widely used in applications such as household appliances and assembly robots for pressure control, monitoring, and assessing the effectiveness of vacuum adsorption.diode
