Lie Detector Head Band
In the wake of immensely growing crime around the world, the best way out to nab a criminal is the use of an accurate lie detection test. The Narco test is one way of lie detection done nowadays. However, researchers from the University of Pennsylvania and Drexel have come up with a new technique for lie detection. This method under research uses infrared images, beaming them directly into the brain. Infrared sensors have been put to many innovative uses in the past, from interactive image generation to treating cancer, to measuring body fat levels. Infrared usage has come a long way, and these functional near-infrared sensors (fNIR), used in a band, monitor the hidden truths in the brain.
