Wearable technology includes a subset of devices that are a bit more internal than the term wearable would suggest. Among these devices are envisioned smart pills and medical-related implants designed to aid in healthcare of all sorts. Latest in this category is a contraceptive chip implant that can be controlled with a remote.
The implant, which must still undergo testing to see whether it is safe and effective, is said to last up to 16 years. Because of its wireless nature, it can also be switched off when needed using a remote, then turned back on later on when required.

This would provide a long-term solution for users, who also have better control over it than modern alternatives, with the on/off toggling ability being something available without the aid of a doctor. The chip measures in at 20 x 20 x 7mm, and is made to be slid beneath the skin on certain areas of the body (the abdomen, for example).
Levonorgestrel hormone is then released in 30 micrograms per day, with 16 years' worth of doses being contained in the chip. Platinum and titanium seal the component containing the hormone. The inspiration for the chip -- namely, its on/off toggling ability -- was inspired by a question Bill Gates asked a couple years ago (inquiring about whether such a device was possible).
If all goes as planned, pre-clinical trials will start in 2015 and the implant will be available in 2018.
