Abstract
Thin-film pressure sensors are disclosed herein. Such sensors include one or more electrodes in contact with a sensing material. As the sensor deforms the capacitance of the sensor varies and is measurable either between two electrodes of the sensor, or between the one electrode of the sensor and an electrode formed by the surface to which the sensor is applied, such as skin. The sensing material can be an ionic material such as an ionic composite including an ionic liquid.
Claims13
A sensor comprising:
- a housing defining a cavity therein, the housing including a top layer disposed between the cavity and the external environment of the housing, the top layer including a first membrane having an electrically conductive surface facing the cavity;
- and
- a solid layer of a sensing material within the cavity, the sensing material being in contact with the electrically conductive surface of the first membrane.
