You can see in 1926 the first pacemaker was invented.

Well, on the left is the IMD, which is Implantable Medical Device, and tonight in the tent you can see it they've exhibited it.

We copy this in the lab by outfitting cell culture systems with electrodes.

In the United States, there are 60,000 people who have a pacemaker that connects to the Internet.

Sometimes these might self assemble in your GI system and be augmented in that reality.

Again, we are making holes in the skull about the size of a dime, putting an electrode in, and then this electrode is completely underneath the skin down to a pacemaker in the chest, and with a remote control very much like a television remote control, we can adjust how much electricity we deliver to these areas of the brain.

Every year, thousands of cochlear implants, diabetic pumps, pacemakers and defibrillators are being implanted in people.

The last one I thought was really, really cool, and I just had to show it to you, it's probably not something that you're going to lose sleep over

The device could be implanted under the scalp to be totally hidden and avoid wire breakage, which occurs if you put it in the chest and you try to move your neck around.
