Device to be implemented in an emergency that utilizes the highest or alternative technology to reduce the time of searching in an emergency to be used by people who live in a risk area of natural disaster or high level of terrorism and are afraid of being trapped under the rubble.
The concept of the device was developed by implementing sound technology based on ultrasonic sound and piezoelectric emitters. The dog whistle was analyzed to define the range of kHz audible by the rescue dogs. This device attached to the human body works as an emitter of ultrasound frequencies that the dogs can hear, and also it can be detected for other specialized electronic devices.
