A recent study has determined a new way to power the devices implanted within the human body and to remain in continuous communication with them. It paves the way to deliver drugs, monitor internal conditions and provide controlled treatment of diseases. Radio frequency waves, which can safely pass through human tissues are used to power the implants. It is estimated that the waves can power the devices located at a distance of 1 cm to 10 cm.
If the sensors are located close to the skin surface, they can be powered from up to 38 metres away. The scientists stated that, “ Even though these tiny implantable devices have no batteries, we can now communicate with them from a distance outside the body. This opens up entirely new types of medical applications ”. They added, “ Having the capacity to communicate with these systems without the need for a battery would be a significant advance.…
