How sensitive are these things to static? Is it true that they can set off a car alarm??? Or was that the earlier models/??
If a baby gets an implant, and he is still growing, does it adjust or does it have to be replaced at some age?
I've never had an issue with static, and I work around (and in) electronics all day. Might be an issue if you were to go down a slide with the implant on, but all it could do is wipe the program - meaning you'd have to go back to the audiologist and redownload the program. Which is why parents of children with CIs generally have them take the CI off at the playground, or look for a playground with metal slides.
The cochlea matures quite early, so implants don't need to be adjusted or replaced for growth. The inside part of an implant is generally under warranty for 10 years (or at least mine is), which gives you some idea of how reliable they expect them to be; and there are people who've had their CIs for 15 years or so and still haven't needed to replace them.
