ABSTRACT:
An electronic pressure-sensing device100comprising a transistor105located on a substrate110. The device also comprises a linker arm115that has a tip120which is configured to touch a contact region125of the substrate that is near the transistor. The device also comprises a pressure converter130that is mechanically coupled to the linker arm. The pressure converter is configured to cause, in response to a pressure change, the tip to impart a force capable of changing an electrical conductivity of the transistor.
