Sensors with potential application in artificial skin structure – review

The human skin, because of its ability to receive stimuli from the outside world, plays a huge role in human life. It is a structure that is responsible for one of the human body senses - the sense of touch, at the same time characterized by resistance to external factors, ensuring thermoregulation and protection against water loss. Recently, attempts have been made to create artificial leather that fulfills the same functions as human skin. The research related to this area attracts a lot of attention. To produce this artificial material, with reproducing as accurately as possible, the functions of human skin, it is necessary to use a range of sensors, such pressure, temperature and humidity sensors. Moreover, all structure and sensor should be printed on flexible, similar to the skin, substrates, which is possible using various methods of printed electronics, such screen printing. This paper presents an overview of available, flexible pressure sensors produced using printed electronics methods, which potential application is the artificial skin structure.
