Abstract
A wearable device is disclosed. The wearable device includes a housing, an attachment device configured to attach the housing to a person, at least one transmit antenna configured to transmit millimeter range radio waves over a 3D space below the skin surface of the person, multiple receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves, and a processor configured to isolate a signal from a particular location in the 3D space in response to receiving the radio waves on the multiple receive antennas and outputting a signal that corresponds to a health parameter of the person in response to the isolated signal.
Claims30
A wearable device, the wearable device comprising:
- a housing;
- a strap configured to attach the housing to a wrist of a person;
- at least one transmit antenna configured to transmit radio waves over a three-dimensional (3D) space below a skin surface of the person;
- multiple receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves;
- and
- a processor configured to isolate a signal from a particular location in the 3D space in response to receiving the radio waves on the multiple receive antennas and outputting a second signal that corresponds to a health parameter of the person in response to the isolated signal;
- further comprising a semiconductor substrate that includes the processor, at least one transmit component, and multiple receive components, wherein the at least one transmit component includes an amplifier that is collocated with the at least one transmit antenna such that a portion of the at least one transmit component overlaps from a plan view perspective a portion of the at least one transmit antenna, and the multiple receive components include mixers that are collocated with respective ones of the multiple receive antennas such that a portion of the multiple receive components overlaps from the plan view perspective a portion of the respective ones of the multiple receive antennas;
- wherein the at least one transmit antenna and the multiple receive antennas are part of a packaged integrated circuit (IC) device that includes the semiconductor substrate and that is located within the strap of the wearable device, wherein the packaged IC device is rectangular in shape and has dimensions of no more than 7 mm by 7 mm;
- wherein the at least one transmit antenna and the multiple receive antennas are configured for radio waves in a frequency range of 122-126 GHz;
- and
- wherein the at least one transmit antenna is a patch antenna that has footprint dimensions of no more than 1.3 mm×1.3 mm and the multiple receive antennas are patch antennas that each have a footprint dimension of no more than 1.3 mm×1.3 mm.
