We describe a simple, miniature, wireless device that can accurately measure pressure fluctuations in the limb compartments of patients at risk of developing ACS. We plan to use temporary indwelling, direct pressure sensors consisting of a Complimentary Metal-Oxide Semiconductor (CMOS) Application Specific Integrated Circuit (ASIC) designed on a battery-less Radio Frequency Identification Device (RFID) platform that is powered with wireless transfer of radio frequency electromagnetic energy and integrated with Micro-Electro-Mechanical-Systems (MEMS) capacitive pressure sensors. This small implantable silicon-based sensor microsystem will be capable of measuring pressures under diverse conditions effecting patients and can be easily used by nurses in hospital settings or by paramedical personnel in cases of accidents, natural disasters, and wartime situations. The proposed sensor microsystem will not interfere with movement of the patient during stabilization, surgery or intensive care stay, and will ultimately, revolutionize the management of trauma victims and minimize the devastating outcomes of compartment syndrome.
