What makes this device very interesting is that it is extremely cheap to make. Replicating the human skin involves creating a device that can detect pressure, touch, proximity, temperature, humidity, flow, and pH levels all at the same time. In order to achieve this, one would expect that highly sophisticated sensors and circuits will be used. That does not happen to be the case. This team used common household items such as sticky notes, napkins, aluminum foils and sponges to create the paper skin. The whole device cost only $1,67 to make.
