They’re close to inventing a mobile phone that can be implanted into a tooth.
Sound, which comes into the tooth as a digital radio signal, is transferred to the inner ear by bone resonance, meaning information can be received anywhere and at any time — and nobody else can listen in
A few thoughts:
1) Cellphones are already intrusive on our homelife as is. Once upon a time we were safe from being called by our bosses when we went out to dinner, or to a theater. Now with our cellphones, we are reachable almost at all times.
But with the tooth phone…even if we have the power not to pick up, what excuse could we give for not doing so?
2) What if it were voice-activated, and we talked in our sleep? We could end up calling someone else, and talking to them all night…and we’d have no recollection in the morning what we told them!!
3) Nobody can listen? Sure. What makes them think the digital radio signal can’t be intercepted? They probably think their cellphone conversations are private, too.
