We propose to design and develop a wireless, light-weight biomedical data acquisition, transmission, and reception system for the interpretation of bioelectrical signals. Examples of biosensing includes sensors measuring voltage signals such as EEG, EKG, EMG, pulse oximetry, blood pressure, and capnography. The proposed WISP system will provide use in battlefield management, in home health care, and in physiological research laboratories with a low cost biosensing capability. When completed, the WISP technology will help fill the gaps between remote biosensing and interoperability with existing communication standards, and between remote biosensing and mobile diagnostic monitoring. The technology will also be applicable to remote sensing in environmental monitoring, distributed process control systems for manufacturing, law enforcement, and in home or office automation. The results will also be applicable to multi-functions wireless nodes interacting with multiple data types of different bandwidth requirements. The system will provide ability to store and process digital data in real-time and will consist of portable low-cost software and hardware modules that can also be easily used in environments of laboratory and clinical research. As a state-of-the-art non-invasive wireless medical instrument, WISP can be used for the biosensing of human physiologic parameters in the presence of noise and is expected to upen huge markets which have heretofore been either only partially penetrated or completely untouched because of the limitaions of the mobility of patients wearing sensors. The design of the WISP system will focus on the following problems: (i) Developing an efficient adaptive micro-controller based conpression of multichannel sensor data. (ii) Developing a real-time mobile TCP/IP network interface for compressed sensor data acquisition over mobile wireless links. (iii) Developing a noise reduction/removal filtering and analysis software. Anticipated Military Benefits/Potential Commercial Applications of the Research or Development: The WISP system will provide use in battlefield management, in home health care, and in physiological research labs with a low cost biosensing capability.
