GAP-CHANGE SENSING THROUGH CAPACITIVE TECHNIQUES |
摘要 |
A gap-change sensing through capacitive techniques is disclosed. In one embodiment, an apparatus includes a first conductive surface and a second conductive surface substantially parallel to the first conductive surface, and a sensor to generate a measurement based on a change in a distance between the first conductive surface and the second conductive surface. The change in the distance may be caused by a deflection of the first conductive surface with respect to the second conductive surface, and the deflection may be a compressive force and/or an expansive force. The sensor may apply an algorithm that converts a change in capacitance to at least one of a change in voltage and/or a change in frequency to generate the measurement. The change in the distance may be caused by a load applied to the surface above the first conductive surface with respect to the second conductive surface. |
