A multidisciplinary Swiss team has developed a tiny implantable chip that can test blood and wirelessly transmit the information to doctors.
Giovanni de Micheli and Sandro Carrara of École Polytechnique Fédérale de Lausanne (EPFL) invented the 14mm-long device. The device is a chip fitted with five sensors and a radio transmitter and is powered via inductive coupling with a battery patch worn outside the body delivering a tenth of a watt in energy. The chip is Bluetooth-equipped to transfer the data picked up by the chip’s radio signals.
The researchers’ goals are to use the chip to monitor five different molecules which may represent five different disease states. This proof-of-concept device has exciting implications for the field of personalized medicine; each person’s biological signals can be recorded and therapy tailored for each individual.
