Life Pyramid / A triangular life detector

An earthquake sometimes destroys whole cities. Life detectors make the search and rescue work more efficient. But a normal life detector has a distance limitation, which means it may not find the victims buried deeper. So how to rescue those people trapped under the ruins? "Life Pyramid" may help. This product is a triangular life detector. Place it on the first floor of the building in earthquake-prone areas. When the earthquake occurs, it will compress and turned on automatically, detecting for signs of life and emitting signals to the rescue team on the ground. This gives hope to the people trapped under the ruins.
