Since wearable technology is all the craze these days (and doesn’t seem to be losing steam), I found this particular article important because of two things: 1) implants are the ultimate wearable and 2) something’s got to power them…unless they could power themselves!

Scientists at Stanford University have implanted a tiny pacemaker in a rabbit and wirelessly powered it to regulate the animal’s heart beat. It’s the first time such a device has been powered this way in a living animal, suggesting that the same technique could run pacemakers or other devices in humans. This would be huge, because now pacemakers and other devices have to be removed and re-installed when they run out of batteries, involving risky surgeries.

Without larger power sources, the devices become much smaller–the size of a grain of rice, as in the case of this pacemaker. Incidentally, the device is charged similar to phone-charging mats using wireless standards like Qi. The obvious downside is some applications is a requirement of consistent charging, but luckily power sources for things like this are everywhere, right?
