Scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have invented a small implantable chip that tell your mobile device to send out a warning when you're on the verge of a heart attack, according to Extreme Tech.

The 14mm device detects five potential warning signs of a heart attack including the presence of the protein tropinin. The lightweight device also measures glucose, lactase and ATP levels. The blood-monitoring device can be also in various medical instances to check up on conditions such as diabetes. The sensor can also be used to measure exact dosage of medicine needed for individual cancer patients.

Doctors can implant the small medical implant under a patient's skin. The Bluetooth-connected device connects to a patient's smartphone to send reports to a doctor whenever a blood test is needed. The device is powered by a battery patch that lies on the patient's skin. This allows for telemedicine, doctors can receive real-time information about their patients, without a visit to the hospital or medical office.
