The Department of Defense (DOD) is seeking proposals for the topic "DIRECT TO PHASE II: Safeguarding Warfighter Medical Data: Secure Encrypted Transmission of Physiologic Monitoring (PhysMon) Data". The objective of this solicitation is to design and manufacture a more secure method of transmitting physiology endpoint data from wearable aircrew physiologic monitoring (PhysMon) devices. The goal is to address the issue of physiological episodes (PEs) experienced by military aircrews, which have been connected to Class A mishaps and medical complications. The Navy requires a more secure method for transmitting data from wearable PhysMon devices, replacing the currently used Bluetooth technology. The technology should be able to transmit data securely, have minimal size and weight, wireless capability, and no interference with flight/safety gear. The solicitation is open to advanced, innovative solutions such as Magnetic Secure Transmission (MST) technology, commercial encrypted wireless links (CEWL) or miniature encrypted wireless links (MEWL), and Ultra Wide Band (UWB) Radio Frequency Identification (RFID) and Wireless Intercom System (WICS). The Phase I of the project involves developing a concept for a workable prototype or design, while Phase II focuses on developing a working prototype and validating its use with human participants. The ultimate goal is to have a solution that meets the performance parameters and can be used in military and commercial applications, such as healthcare providers, long-haul trucking, and recreational use. The global wearable medical device and fitness-tracker market presents significant opportunities for the adoption of this technology.
