"I always wondered how true that is, and if we really have perfected lie detecting technology. If so, why not just wear a lie detector on our wrist? This is the concept behind the Truth Wristband.
The Truth Wristband measures the user’s galvanic response to a question, and will go from blue to red which will reveal if the user is telling the truth.
Now, there is a question of who would use such a device. Obviously it has the potential to make interrogation much easier. I suppose someone could choose to wear these things. That would be quite a conversation piece, and a true test of your character."
