Ultraviolet Communication for Medical Applications

Under this Phase II SBIR IST will extend research conducted in Phase I to demonstrate several viable configurations for UV non-line-of-sight (UV NLOS) communication. Under Phase I, IST performed a survey of literature and an investigation of off-the-shelf and emerging technology. IST also worked to optimize its Plasma-shell technology as a key UVC light emitting component of the transceiver. It was concluded in Phase I, that currently there is a trade-off between power and performance. System sensitivity and speed can be increased if one is willing to employ large arrays of emitters and sensitive detectors. However, this increases power consumption and system weight. Relatively light weight low power systems can be fabricated at the expense of distance, and communication speed. Under Phase II IST will investigate the development of a system that employs both architectures to achieve optimum results. The system will consist of a powerful stationary hub anchored to a vehicle or building in communication with small devices attached to medical equipment or personnel. The system will feature a networking capability that allows the small devices to communicate amongst themselves and relay messages to the hub.
