The capacitive sensor comprises a seat frame connector for connecting the control and evaluation circuit to the seat frame of the vehicle seat. The control and evaluation circuit is configured to operate in a second mode of operation, during which it measures electrical current flowing into the seat frame connector.

Abstract: The present disclosure provides a method and apparatus for a capacitive force sensor utilizing a magnetic spring. The force is applied across a body and a moveable element that are coupled by the magnetic spring. The moveable element is configured to vary the capacitance of a variable capacitor. A sensing circuit, electrically coupled to the variable capacitor, provides a force signal characteristic of the applied force. In application to a stylus pointing device, the moveable element is coupled to a moveable tip of the stylus. The force signal, which is characteristic of the force applied to the tip of the stylus, may be used to control an application executed on a host electronic device.

Abstract: Flexible force/pressure sensors for producing electrical output signals proportional to forces or pressures exerted on the sensor include a thin, elastically deformable foam pad laminated between a pair of electrically conducive fabric sheets. A piezocapacitive embodiment of the sensor utilizes an elastically deformable perforated open-cell polyurethane foam pad preferably saturated with glycerin to increase the capacitance of the sensor. The piezocapacitive sensor section is preferably stacked onto a piezoresistive section having a second open-cell foam pad containing piezoresistive carbon particles to form a hybrid piezocapacitive/piezoresistive sensor. A third, “leaky dielectric” embodiment of a sensor includes a single open-cell foam pad which contains both a dielectric liquid and conductive particles. A low frequency such as d.c. to a few hertz is applied to a sensor to determine piezoresistive response of the sensor to forces or pressures and a higher frequency such as 30 KHz is applied to determine piezocapactive response.
