In an article published in the Science and Technology Daily on July 28, Qi Qingjie, a leading scientist at China Coal Engineering and Technology Group, announced that field test results showed that the life detector can transmit signals through non-metallic materials such as brick walls, wooden boards, concrete and soil.

The detector can "catch" the survivors' vital signs, such as breathing and heartbeat, within minutes and at a distance of up to 30m.

This device can be used in search and rescue operations after earthquakes, geological disasters and landslides.

The research team conducted life signal detection and location experiments in various post-disaster simulation scenarios, such as high-rise building collapse caused by earthquakes, to test the effectiveness and accuracy of the life detector.
