The eShirt® System
A complete physiologic picture, worn like your favorite undergarment.
The eShirt® is a fully integrated wireless, non-invasive smart garment that will continuously and simultaneously monitor physiologic functions such as heart rate, respiratory rate, ventilation, body position, activity level, blood oxygen saturation and skin temperature to create a complete ambulatory picture of a patient's physiologic status in real-time. The eShirt® will use Bluetooth and communicate to a smart phone for bidirectional data transmission. The entire platform is designed for efficiency, data quality, upgradability and ease of use.
Designed to disappear.
Worn under regular clothes, eShirt® fits like your favorite undergarment. The fabric keeps you cool, dry, and chafe-free. It's machine washable, quick-drying, durable, and easy-care.

Alerts that reach the right people, at the right time.
A patient-status value is calculated on the smartphone from programmable thresholds. Current and previous heart rate and respiratory rate values combine with activity level to establish the patient's status for their care provider. Status alerts are sent via email or SMS at programmed intervals or when limits are exceeded.
