Virtual EM was awarded a SBIR Phase I contract by NSF for developing a cell-based wireless sensor for detection of Improvised Explosive Devices (IEDs). The sensor is an “electronic nose” sniffing explosives and warning the operator (equipped with a hand-held device) at a 100 meter distance. University of Maryland is developing the sensor front-end, which relies on olfactory neuron cells. The sensor will be integrated with Virtual EM’s ZigBee technology for stand off detection.
