First Claim
Patent Images
1. A body-mounted photoacoustic sensor unit comprising:
- a light source, wherein the light source is configured to transmit light into a subject, and wherein the transmitted light is capable of generating a photoacoustic response in the subject;
a photoacoustic detector configured to detect the photoacoustic response; and
a support assembly configured to secure the photoacoustic sensor unit to the subject and coupled to the light source and photoacoustic detector, wherein the light source and photoacoustic detector are fixably located relative to a target area of the subject.

Abstract
A body-mounted photoacoustic sensor unit may use photoacoustic sensing to determine one or more physiological parameters of a subject. The body-mounted photoacoustic sensor unit may fixably locate a light source and photoacoustic detector relative to a target area. The photoacoustic detector may detect an acoustic pressure response generated by the application and absorption of light from the light source.
