Many people die every year from cardiovascular failure, even though they could be saved by first responders performing chest compressions. "Rescue Aid", a pressure-measuring mat that is placed on a victim's upper body, allows rescuers to correctly apply pressure depth and rate through simple guidance.
Star-shaped dielectric deformation sensors made of soft silicone integrated into the mat measure the pressure depth. The sensors are connected by cable to the electronics and LEDs, and a light code indicates whether sufficient pressure is being applied. An acoustic signal sets the rhythm of the compression.
