Gold-finger !

Two fingers are holding a small piece of metall. One finger is equipped with the nanomesh sensor.

Scientists from the Technical University of Munich (TUM) and the University of Tokyo have developed an ultrathin pressure sensor that can be attached directly to the skin. It can measure how fingers interact with objects to produce valuable data for technological or medical applications. The sensor has an unnoticeable effect on the users’ sensitivity and ability to grip objects, and it is highly resistant to disruption from rubbing.

A layer of polyurethane nanofibers serves as a passivation and carrier layer, followed by an ultra-thin layer of gold mesh, an intermediate layer of parylene-coated polyurethane nanofibers and finally another layer of gold mesh. Make up the sensor thats applied to the finger tips.

The nanomesh, constructed from polyvinyl alcohol (PVA) nanofibers and a gold (Au) layer, adheres to the skin when sprayed with water, dissolving the PVA, as depicted in the enlarged diagrams at bottom
