摘要： A strain characterization system includes a strain sensor having first and second electrodes that sandwich a dielectric layer to form a capacitor; a power source configured to inject a signal VAC between the first and second electrodes of the strain sensor; and a controller configured to control the power source and to select a frequency of the power source. The controller is configured to select first to third different frequencies for determining a strain magnitude, a strain location, and an extent of a strain area.

摘要： In an example, a vehicle seat sensor system includes a vehicle seat, a flexible seat sensor, and an electronics unit. The vehicle seat includes a seat surface. The flexible seat sensor is disposed within a deformable distance from the seat surface and includes one or more signal electrodes, one or more ground electrodes, one or more dielectric layers, and one or more capacitors. Each capacitor is formed by a combination of a corresponding signal electrode and a corresponding ground electrode with a corresponding dielectric layer positioned between the corresponding signal electrode and the corresponding ground electrode. The electronics unit is connected to the flexible seat sensor and is configured to electrically communicate with the flexible seat sensor. The flexible seat sensor is configured to provide a capacitive output proportional to an amount of pressure applied to the flexible seat sensor.

摘要： A touch sensor detector system and method incorporating an interpolated sensor array is disclosed. The system and method utilize a touch sensor array (TSA) configured to detect proximity/contact/pressure (PCP) via a variable impedance array (VIA) electrically coupling interlinked impedance columns (IIC) coupled to an array column driver (ACD), and interlinked impedance rows (IIR) coupled to an array row sensor (ARS). The ACD is configured to select the IIC based on a column switching register (CSR) and electrically drive the IIC using a column driving source (CDS). The VIA conveys current from the driven IIC to the IIC sensed by the ARS. The ARS selects the IIR within the TSA and electrically senses the IIR state based on a row switching register (RSR). Interpolation of ARS sensed current/voltage allows accurate detection of TSA PCP and/or spatial location.

摘要： A sensor configured to sense when a force is applied to a surface includes a capacitive structure having a first conductive layer, a dielectric layer, and a second conductive layer. The dielectric layer is overlain on the first conductive layer and the second conductive layer is overlain on the dielectric layer. A glass superstrate has a first side and a second side, with the first side overlain on the second conductive layer. The force is applied to the second side of the glass superstrate. The force results from an object attached to the second side of the glass superstrate. The force causes capacitance changes between the first and second conductive layers. The force can be compressive or tensile, depending on whether the object is attached by magnet or adhesive.
