Publication number: 20230309827Abstract: Certain pressure sensor devices are much smaller than prior art devices, yet are at least as sensitive as the prior art devices. A capacitive pressure sensor can include a flexible substrate that permits bending of a pressure sensing region without significantly affecting operation thereof. The pressure sensor can include a flexible membrane in which an electrode is sandwiched between two layers of polymeric material. The sandwiched electrode can be extremely close to a reference electrode so as to provide for highly sensitive capacitance readings, yet the membrane can be restricted from contacting the reference electrode under high pressure condition.Type: ApplicationFiled: October 19, 2022Publication date: October 5, 2023Applicants: The Jackson Laboratory, Purdue Research FoundationInventors: Pedro P. Irazoqui, Dohyuk Ha, William J. Chappell, Simon W.M. John
