Abstract
A wearable apparatus for sensing movement of a wearer's body is disclosed. The wearable apparatus comprises a flexible substrate for conforming about the wearer's body, and a capacitive sensor attached to the flexible substrate, the capacitive sensor comprising a transmitter electrode and a receiver electrode arranged in opposition on opposite sides of the flexible substrate, the transmitter electrode being arranged to capacitively couple to the receiver electrode.
Claims15
A wearable apparatus for sensing movement of a wearer's body, the wearable apparatus comprising:
- a flexible substrate for conforming about a wearer's body, and
- a capacitive sensor attached to the flexible substrate, the capacitive sensor comprising a transmitter electrode and a receiver electrode arranged in opposition on opposite sides of the flexible substrate, the transmitter electrode being arranged to capacitively couple to the receiver electrode.
A method for sensing movement of a wearer's body using a wearable apparatus, the method comprising:
- conforming a flexible substrate of the wearable apparatus about a wearer's body, the flexible substrate comprising a capacitive sensor attached to the flexible substrate, the capacitive sensor comprising a transmitter electrode and a receiver electrode arranged in opposition on opposite sides of the flexible substrate,
- applying, using a signal generator, input electrical signals to the transmitter electrode of the capacitive sensor to cause the transmitter electrode to capacitively couple to the receiver electrode of the capacitive sensor,
- detecting, using a signal detector, output electrical signals from the receiver electrode, and
- sensing, using a capacitance sensing circuit, changes in capacitance of the capacitive sensor.
