Implantable Chip Monitors Patients, Transmits Results Over Cellular Network

The human body manufactures thousands of substances, some of which can be used as indicators of health status. A team of scientists from the École Polytechnique Fédérale de Lausanne (EPFL) has developed a tiny device that can analyze the concentration of these substances in the blood. Implanted just beneath the skin, it can detect up to five proteins and organic acids simultaneously, and then transmit the results directly to a doctor's computer. This method will allow for a much more personalized level of care than traditional blood tests can provide. Health care providers will be better able to monitor patients, particularly those with chronic illness or those undergoing chemotherapy. The implant is only a few cubic millimeters in volume but includes five sensors, a radio transmitter, and a power delivery system. Outside the body, a battery patch provides 1/10 watt of power, through the patient's skin.

    00:00:04 we have uh fabricated an implantable chip that can be placed under the skin to help daily medicine that is we can monitor patients from Far whether they have chronic or transient conditions this can be seen by a doctor in a remote place the chip is placed in the intertial tissue and it comes in contact with fluids in the body and the sensors react to the presence of particular

    00:00:30 compounds in these fluids detect them and then sense the measurements outside this uh system host seven sensor including seven electrochemical and molecular sensors the chip implanted is batteryless it is powered by a patch an intelligent patch which is located on top of the skin and this patch transmit the power by an inductive link to the implanted and receive the data from the

    00:00:57 implanted device then the patch transmit thanks to a Bluetooth connection the data to a smartphone or an iPad allowing a tele medicine uh chain it's very important for patients to measure metabolites in the bloodstream and these are measured by this chip and this information can be very important for example to detect possible cardiac conditions the monitoring of metabolites

    00:01:24 in the bloodstream or in the intertial tissues is a key element in order to do predictive medicine this located under the skin of the patients can predict heart attack in advance of some hours thanks to some metabolized L troponin that are released by the heart when it became suffering for an art attack with this chip also we can monitor glycemic and variation of glycam that can be

    00:01:47 important in the case of Crisis for diabetic patients the chip is really a Nanos system there are probes built with nanotechnology that can sense compounds in the blood and then there's an electronic part that process this information and transmit it outside the body
