Over the recent years, there has
been an upsurge in the market for wearable electronic devices. Japanese based
biomedical engineers have developed a flexible, biocompatible, adhesive gel
The gel patch has the capacity to
sense the internal and the external electrophysiological biological signals.
The adhesive fixes a fine network of detectors to the surface even when it is
not static, for ex: an internal organ or a joint. A thin sheet of plastic is
printed with a range of sensors that are 4 mm apart. The detector obtains
reading from this sensor and the accuracy of the readings depends upon the
sensors. The outcome of all this is a flexible patch, which fits in the palm.
It can accommodate up to 144 sensors.
The adhesive gel patch - as it is
called - is still in the preclinical testing stage promises a comfortable,
long-term, classy biometric medical device. Also it can be used internally as
well as externally.
Researchers have demonstrated that the device holds for
further than three hours to the dynamic, wet surface of heart muscles. This
enables dependable measurement of biological signals.
