Objects that know when they are touched

Touche is a new device that senses when objectss are touched. This works on humans, screens, liquids, and everday objects. Basically, it means everything. Touche requires a single wire to be attached in order to catch the movement. For example, a door knob will know whether to open or not based on how its being gripped. This new device is amazing because it'll keep you safe. Touché is a form of capacitive touch sensing, the same principle underlying the types of touchscreens used in most smartphones. But instead of sensing electrical signals at a single frequency, like the typical touchscreen, Touché monitors capacitive signals across a broad range of frequencies. Touche may enable us from key boards to computers one day. Touche is really cool because its basically another way of keeping yourself safe and monitored. Touche will lock doors depending on the grip and in the video I watched Touche is teaching kids how to eat with the proppar utensil. It buzzes when the wrong utensil is used and says "good job" when the correct utensil is used. This invention is really cool and I would love to be able to have the use of it.
