Human Touch Elevator switches

[sanky1408]

I read that they are just like glow bulb electrical testers which requires a human touch to let us know the presence of electricity.

 

So i started wondering if there is any way we can simulate the effect without a human touch, i mean say from a distance like a remote. Is that possible with a capacitance circuit in elevator?

that would be realy cool. so that from down the hall you could activate the elevator and not have to wait as long.

 

ill see if there is something on it somewhere. but you should try inventing it.

Unfortunately, even if this were economically feasible, it could have significant privacy concerns if it could detect people from far enough away to activate.

perhaps with a grounded super-soaker you could do it, but you`d have to make certain the water stream didn`t break up into droplets and remain as a solid unbroken connection.
