Abstract
A pressure sensor includes a substrate, a pressure sensing element, a first signal line, a second signal line, an elastomer, and an opposite substrate. The pressure sensing element includes first and second resistors connected in series, a third and fourth resistors connected in series, a first switch component, and a second switch component. The first and second resistors are connected in parallel to the third and fourth resistors. The first switch component is electrically connected between the first and second resistors. The second switch component is electrically connected between the third and fourth resistors. The first to fourth resistors at least partially overlap with a cavity of the elastomer, which can increase the stress on the first to fourth resistors when the pressure sensor is under pressure, thereby improving the sensitivity of the pressure sensor.
