Key result
A compact portable microwave life-detection device operating at 1.15 GHz accurately detected vital signs through 1.5 m of highly dense construction materials and 10 m of standard density materials.
A novel portable microwave device operating at 1.15 GHz can detect vital signs through thick construction materials, offering potential utility in search and rescue operations.
In this letter, an ultra-sensitive compact portable microwave life-detection device is introduced and implemented with promising results. By utilizing Doppler effect-based systems, vital signs such as heartbeats and breathing can be detected and can be used for finding survivors under earthquake rubble, injured soldiers on battlefields and as lie detection device. This device is tested in both simulated and realistic situations, and it can accurately detect crucial signs of life through highly dense construction materials of about 1.5 m thick and standard density materials of about 10 m while operating at 1.15 GHz center frequency.
