## Abstract

A smart bra to detect abnormal breast tissue with a plurality of light emitters which transmit near-infrared light into breast tissue and a plurality of light receivers which receive the light after it has passed through breast tissue, wherein changes in light intensity or spectral distribution in the light caused by passing through the breast tissue are used to identify abnormal breast tissue.

## Claims

### Claim 1

A smart bra to detect abnormal breast tissue comprising:
a smart bra which is configured to be worn on a person's breasts;
wherein the smart bra further comprises a concave hub-and-spoke array of sinusoidal wires, wherein central ends of different spokes in the array are different distances from a center of the array;
wherein the smart bra further comprises a plurality of light emitters connected to the wires and wherein the light emitters are configured to transmit light into breast tissue; and
wherein the smart bra further comprises a plurality of light receivers connected to the wires and wherein the light receivers are configured to receive the light after it has passed through breast tissue.

### Claim 2

A smart bra to detect abnormal breast tissue comprising:
a smart bra which is configured to be worn on a person's breasts;
wherein the smart bra further comprises a concave array of optical sensor clusters;
wherein a cluster in the concave array of optical sensor clusters further comprises a first quantity of light emitters which are configured to transmit near-infrared light into breast tissue and a second quantity of light receivers which are configured to receive the light after it has passed through breast tissue, wherein the second quantity is less than the first quantity;
wherein each cluster further comprises a first quantity of light emitters which are configured to transmit near-infrared light into breast tissue, wherein each cluster further comprises a second quantity of light receivers which are configured to receive the light after it has passed through breast tissue, and wherein the second quantity is less than the first quantity;
wherein the smart bra further comprises a power source; and
wherein the smart bra further comprises a data processor;
wherein the smart bra further comprises elastic electroconductive yarns, threads, or filaments; and
wherein the optical sensor clusters are connected to the power source and/or to the data processor by the yarns, threads, or filaments.

### Claim 3

A smart bra to detect abnormal breast tissue comprising:
a smart bra which is configured to be worn on a person's breasts;
wherein the smart bra further comprises a plurality of light emitters which are configured to transmit light into breast tissue;
wherein the smart bra further comprises a plurality of light receivers which are configured to receive the light after it has passed through breast tissue; and
wherein the smart bra further comprises a plurality of transparent light guides with a durometer level less than 50 which are configured to be between the light emitters and the surface of the person's body and/or between the light receivers and the surface of the person's body.
