A group of Japanese scientists has sensors directly developed organs may be made. This has the advantage that weak electrical signals in the body to be absorbed which could otherwise go unnoticed.
A publication in which the discovery is explained, is published this month in the scientific journal Nature Communications. The Japanese researchers describe a gel-like substance that electrical signals can be captured. The material is according to the creators, suitable to directly on the soft, wet tissues, and it is therefore possible to electrical signals on the surface of bodies can be measured.
Because most of the sensors which are electrical pulses, measuring of a hard material, it is usually outside the body to be applied, making the signals only indirectly be measured. Also, as the weakest signals are lost. With the by the Japanese researchers developed materials should therefore be possible to use biological signals are more accurate to follow.
The material used is pva, that the body does not reject, is very flexible and is good on different surfaces can attach. The scientists test their on pva-based sensors in rats. The experiments show that sensors that are at the heart of the rat to be stuck three hours of continue sitting. Also the read-out electrical signals would be accurate.
There is still much research is needed before the flexible organenplakkers can be applied in people. The scientists still need long-termijnstudies do to see how long the sensors continue to work. They also need the security show before studies in humans are allowed. Such sensors would be able to serve for pacemakers and brain signals to read.
