A movement-sensitive capacitive sensor includes a first conductive element and a second conductive element positioned adjacent to the first conductive element. The sensor also includes a first protective insulator and a second protective insulator sealed to the first protective insulator with the first conductive element and the second conductive element positioned between the first protective insulator and the second protective insulator. The sensor further includes a circuit configured to calculate, over time while a person is occupying the movement-sensitive capacitive sensor and moving while occupying the movement-sensitive capacitive sensor, capacitance values between the first conductive element and the second conductive element. The circuit also is configured to determine an occupancy state of the movement-sensitive capacitive sensor based on the calculated capacitance values, determine movement-sensitive measurements based on the calculated capacitance values, and transmit output based on the determined occupancy state and the determined movement-sensitive measurements.

Non-contact, capacitive, portable presence sensing

A force-sensitive capacitive sensor that includes a first conductive plate, a second conductive plate that is spaced apart from the first conductive plate, and a compressible dielectric insulator positioned between the first conductive plate and the second conductive plate. The sensor also includes a first protective insulator, a second protective insulator sealed to the first protective insulator to encase the first conductive plate, the second conductive plate, and the compressible dielectric insulator, and a circuit attached via wires to the first conductive plate and the second conductive plate. The sensor may also include electromagnetic shielding. The circuit is configured to sense a change in capacitance between the first conductive plate and the second conductive plate caused by compression of the compressible dielectric insulator resulting from a person occupying the sensor or a support surface positioned above the sensor, and transmit output based on the sensed change in capacitance.
