Researchers just released information on a new half-inch long medical sensor that is implanted under the skin, and can send data back to your smartphone via Bluetooth. This technology will greatly benefit those who have to test their blood on a regular basis like diabetes and cancer patients.

The device is capable of streaming back information on things like blood glucose levels, monitoring cholesterol and even predict heart attacks before they occur by sensing minute changes in blood chemistry. The sensor is also able to aid in the treatment of cancer patients by monitoring chemotherapy treatments using five built in sensors.

The device has already been successfully tested on animals, and researchers are hoping to begin human trials soon. The first patients to trial the device will be those whose treatment requires a large amount of blood testing to be done. As someone who has some blood sugar issues, I would love to be able to test my glucose levels without having to stick my finger ever again.
