welcome 2 ma' blog.... -Sujit Kumar Nath: DRDO develops “Sanjeevani”- A Technology to detect life trapped under debris
Defence Research and Development Organization (DRDO) has developed a special technology called Acoustic Life Detector or Sanjeevani to detect human beings trapped under the debris of buildings after earth quakes or land slides.
How it works
The Acoustic Life Detector uses highly sensitive acoustic sensors and audio signals to listen to the low frequency sounds from below the debris.The acoustic sensors are designed to detect a range of low frequency signals like hitting, tapping, scratching or moaning sounds made by the victims trapped in the rubble of houses and other structures.
Applications
The Life Detector can detect human lives to the depth of six to eight metres below the debris and would be provided to disaster management teams, earth quake response forces and police and fire services department, landslide prone areas.
