A micro piezo-electric air valve is used to form a skin interface system composed by a matrix of valves interconnected that bring temperature and touch sensorial experience to people through the skin's tactile, pressure and temperature biological sensors by means of micro air jet formations and/or air bubble formations over the skin. The piezo-electric air valve is specially designed to sensitize a small area of the skin of the user by quickly delivering a specific volume of air following a selected pattern, for example a pixel of an image that is processed by a computer system and converted into electric signal that opens or closes the piezo-electric air valve causing the air to flow. Such a skin interface system can be used by blind people to interpret a scene in front of them when using a video camera. or for use as a suit for therapeutic use and gaming.
