发明名称 Semiconductor based pressure sensor
摘要 The present invention provides a pressure sensor. The pressure sensor comprises a substrate with several support structures attached to the substrate. The pressure sensor further includes a strut structure integrated with a heating element. The strut structure is engaged with the support structures so as to create an air gap between the heating element and the substrate. The heating element has an electrical resistance proportional to changes in air pressure in the air gap.
