In response to the Navy’s desires to acquire electrocardiogram (ECG) and other physiological measurements on divers underwater, Quantum Applied Science and Research (QUASAR) is developing waterproof electrodes and other sensors for a Diver Biometric Device (DBD) to provide ECG, respiration, skin temperature, activity and other measurements in saltwater and at depth. QUASAR is a world leader in noninvasive biosensing systems, created by integrating our sensors with precision hardware and sophisticated algorithms. The first DBD wireless belt prototype is complete and will be validated in this Phase II program. QUASAR seeks partners to transition the Phase II system with QUASAR providing design support. QUASAR has manufacturing capability for small orders, but needs support for volume production.
