Abstract
Examples are disclosed that relate to a disposable cover for an object, wherein the cover includes a passive sensing circuit loop. The sensing circuit loop is configured to inductively couple with a reusable sensor readout device that provides power and signal processing. The reusable sensor readout device wirelessly measures a sensor element printed as part of the sensing circuit loop through the inductively coupled channel. In one example, a disposable glove for a human hand includes a sensing circuit loop printed on the disposable glove.
Claims19
A disposable glove for a human hand, comprising:
- a sensing circuit loop printed on the disposable glove, the sensing circuit loop including
- a motion sensor element printed on a finger joint portion of the disposable glove, and
- an inductive coil printed on a wrist portion of the disposable glove.
A disposable glove for a human hand, comprising:
- a sensing circuit loop printed on the disposable glove, the sensing circuit loop including
- an inductive coil printed on a wrist portion of the disposable glove, and
- one or more of a capacitive sensor element and a resistive sensor element printed on a finger joint portion of the disposable glove.
A sensor readout device, comprising:
- an inductive coil;
- and
- a controller configured to:
- drive the inductive coil with an electrical current to inductively couple the inductive coil with an inductive coil of a sensing circuit,
- vary a frequency of the electrical current to perform a frequency scan of the sensing circuit,
- measure capacitance of a capacitive sensor element based on electrical behavior during the frequency scan,
- measure resistance of a resistive sensor element based on electrical behavior during the frequency scan,
- convert the measured capacitance into a corresponding first physical quantity, and
- convert the measured resistance into a corresponding second physical quantity.
