The sensor is made on a semiconductor substrate covered with an electrically insulating layer. The electrically insulating layer separates a thermocouple from the substrate. It includes a first portion presenting a first value of capacitance per unit area and a second portion presenting a second value of capacitance per unit area, which is lower than the first value. The sensor includes first and second output terminals connected to the thermocouple. The first output terminal includes a first capacitor having a first electrode formed by a first leg made of an electrically conducting material. The second electrode of the capacitor is formed by a part of the substrate facing said first leg and separated from the first electrode by the first portion of the electrically insulating layer. The first leg connects the thermocouple while overlapping the second portion of the electrically insulating layer.
Abstract:
The present invention, in one embodiment, provides a method of measuring pressure or temperature using a sensor including a sensor element composed of a plurality of carbon nanotubes. In one example, the resistance of the plurality of carbon nanotubes is measured in response to the application of temperature or pressure. The changes in resistance are then recorded and correlated to temperature or pressure. In one embodiment, the present invention provides for independent measurement of pressure or temperature using the sensors disclosed herein.
