Brainwave Detector

Brainwave detector, based on brain-scanning or brain fingerprinting technologies, could be used for lie detecting. This technique uses an electroencephalograph (EEG) to measure a person’s brain activity when they look at objects or pictures of evidence. If they recognize something their brainwaves change. An investigator can use this method if he had a piece of evidence that only the perpetrator of a crime would recognize. Simply showing the evidence to the suspect would produce brainwaves that would betray his guilt or innocence.
