Washable wearable biosensor
First Claim
1. A system for monitoring physiological data comprising:
- a wearable washable breathable garment adapted to be worn in multiple positions on the human body;
a plurality of sensors attached to said garment for acquiring sensor data indicative of one or more of the following characteristics of said human body;
heart rate variability, motion, electrodermal activity, and temperature, wherein at least one of said sensors is an electrodermal activity sensor that includes an op-amp circuit with non-linear feedback that automatically scales gain to compensate for a range in skin conductance;
a wireless communication unit attached to said garment for transmitting physiological data including or derived from said sensor data via a wireless communications link to a remotely located utilization system; and
a processor attached to said garment or included in said remotely located utilization system for analyzing said physiological data to identify patterns manifested by said physiological data indicative of the condition of said human body.

Abstract
A washable, wearable biosensor that can gather sensor data, communicate the sensed data by wireless protocols, and permits the analysis of sensed data in real-time as a person goes about their normal lifestyle activities. The biosensor can be worn in multiple positions, can be put on or removed quickly without having to apply or remove gels and adhesives, and provides a snug, comfortable fit to gather data with minimal motion artifacts. The textile, wearable device can support integrated photoplethysmography, skin conductance, motion, and temperature sensors in a small wearable package. The supported sensors may be coupled to utilization devices by channel-sharing wireless protocols to enable the transmission of data from multiple users and multiple sensors (e.g. both sides of body, wrists or hands and feet, or multiple people). An on-board processor, or the receiving utilization device, can map patterns of the physiological and motion data to signals or alerts such as a likely seizure, drug craving, or other states that the wearer may exhibit or experience. The sensor data may be sent by wireless transmission and received by a mobile phone or other personal digital device, a computer, a favorite toy, or another wearable device. The sensors may include multiple photoplethysmographs and/or one or more EDAs which perform a time-domain measurement of skin conductance.
