DEVICES, METHODS AND SYSTEMS FOR EAR-BASED PHOTOACOUSTIC PLETHYSMOGRAPHY

This abstract first appeared for US patent application 18339170 titled 'DEVICES, METHODS AND SYSTEMS FOR EAR-BASED PHOTOACOUSTIC PLETHYSMOGRAPHY

Original Abstract Submitted

An apparatus may be configured to control a light source system residing in or on a first support structure portion of the apparatus to transmit light through an ear volume residing between a first ear portion and a second ear portion. The apparatus may be configured to receive, from a receiver system residing in or on a second support structure portion of the apparatus proximate the second ear portion, receiver system signals corresponding to acoustic waves caused by a photoacoustic response to light emitted by the light source system of a) a blood vessel residing within the ear volume, b) blood within the blood vessel, or a combination thereof. The control system may be configured to estimate one or more cardiac features based, at least in part, on the receiver system signals.
