Abstract:
1. A micro-electro-mechanical-structure (MEMS) temperature sensor comprising: a suspended spiral comprising a material having a positive thermal expansion coefficient, wherein a central end of said suspended spiral is fixed to a substrate and a peripheral end of said suspended spiral moves upon thermal expansion; an actuator configured to be azimuthally rotated about a pivot point by said peripheral end of said suspended spiral and including a set of at least one conductive rotor azimuthal fin; and a set of at least one conductive stator azimuthal fin that is fixed to said substrate, wherein capacitance between said set of at least one conductive rotor azimuthal fin and said set of at least one conductive stator azimuthal fin varies with an azimuthal rotation of said actuator.
