Abstract

A device for monitoring a health parameter in a person is disclosed. The device includes a semiconductor substrate, at least one transmit antenna configured to transmit millimeter range radio waves over a 3D space below the skin surface of a person, multiple receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves, wherein the semiconductor substrate includes circuits for processing signals received on the multiple receive antennas, wherein processing signals includes mixing signals of two different frequencies, and wherein the semiconductor substrate includes at least one output configured to output a signal that corresponds to a health parameter of a person in response to received radio waves.

First claim

What is claimed is:

1 . A device for monitoring a health parameter in a person, the device comprising:
a semiconductor substrate; at least one transmit antenna configured to transmit millimeter range radio waves over a three-dimensional (3D) space below the skin surface of a person; multiple receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves; wherein the semiconductor substrate includes circuits for processing signals received on the multiple receive antennas, wherein processing signals includes mixing signals of two different frequencies; and wherein the semiconductor substrate includes at least one output configured to output a signal that corresponds to a health parameter of a person in response to received radio waves.

2 . The device of claim 1 , 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.

3 . The device of claim 1 , wherein the semiconductor substrate includes a mixer to mix a signal at 120 GHz with a signal at 2-6 GHz for transmission from the at least one transmit antenna.

4 . The device of claim 1 , wherein the semiconductor substrate includes a mixer to mix a signal received at a receive antenna at 122-126 GHz with a signal at 120 GHz to produce a signal at 2-6 GHz.

5 . The device of claim 1 , wherein the semiconductor substrate includes a first mixer to mix a signal received at a receive antenna at 122-126 GHz with a signal at 120 GHz to produce a signal at 2-6 GHz and a second mixer to mix the 2-6 GHz signal with a 2-6 GHz+2.5 MHz signal to produce a 2.5 MHz signal.

6 . The device of claim 1 , wherein the at least one transmit antenna and the multiple receive antennas are located within a footprint of the semiconductor substrate.

7 . The device of claim 1 , wherein the multiple receive antennas are located at opposite corners of the semiconductor substrate.

8 . The device of claim 1 , further comprising a semiconductor substrate with at least one transmit component and multiple receive components, wherein the at least one transmit antenna is collocated with the at least transmit component and the multiple receive antennas are collocated with respective ones of the multiple receive components.

9 . The device of claim 1 , wherein the at least one transmit component and the at least one transmit antenna comprise at least two transmit components and at least two transmit antennas and wherein the multiple receive components and multiple receive antennas comprises four receive components and four receive antennas and wherein receive components and receive antennas are collocated at opposite corners of the semiconductor substrate.

10 . The device of claim 1 , wherein the at least one transmit antenna has footprint dimensions of no more than 1.3 mm×1.3 mm and the multiple receive antennas each have a footprint dimension of no more than 1.3 mm×1.3 mm.

11 . The device of claim 1 , wherein the semiconductor substrate is rectangular in shape and has dimensions of no more than 7 mm by 7 mm.

12 . The device of claim 1 , further comprising means for isolating 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 blood glucose level in the person in response to the isolated signal.

13 . The device of claim 1 , wherein the health parameter is a blood glucose level.

14 . The device of claim 1 , wherein the health parameter is a blood pressure.

15 . The device of claim 1 , wherein the health parameter is a heart rate.

16 . A wearable device including the device of claim 1 .
