Physical Optics Corporation — Department of Defense SBIR Phase II: A16-053

Description

To address the Army’s need for a secure disposable patch that generates a photoplethysmogram (PPG) waveform, Physical Optics Corporation (POC) proposes to continue the development of a new ruggedized Secure, Miniature, Algorithm-Enhanced Low-Power Low-Profile Photoplethysmogram (SMALL-PPG) patch proven feasible in Phase I. SMALL-PPG is based on a novel integration of POC’s physiological monitoring technology, miniaturized electronics and sensors, patient status algorithms, and wireless interface. Specifically, the innovation in electronics miniaturization, signal processing algorithms, and reflective PPG configuration enables the patch to measure and transmit a PPG waveform to an end-user device (EUD) for additional analysis and provide patient status remotely. Building on POC’s previous successes in wearable electronics and physiological sensors, POC successfully researched, designed, and demonstrated a prototype in Phase I that can wirelessly transmit data to an EUD. The prototype generates a high-accuracy PPG waveform and derives physiological parameters in real time and is ready for initial testing in the Phase I Option. In Phase II, POC will develop a ruggedized SMALL-PPG prototype that can be demonstrated in a field environment with soldier medical attendants. Collaboration with military end-users will result in transition of the SMALL-PPG technology proof-of-concept evaluations in Phase III.
