| Abstract | ||||
| The Triboelectric Nanogenerator (TENG) has been very important ever since it was invented back in 2012. Multiple designs have been made to use it in harvesting energy or in making self-powered sensors. One of those self-powered sensors are self-powered touch buttons. It can be made by adhering a layer of dielectric on an electrode, then the charge is generated when it is touched by a human finger. That charge can then flow to an electrical ground generating a usable signal. This study aims to investigate multiple designs and material choices for a TENG-based button which can be used in hospitals. It was found that materials close to the bottom of the triboelectric series such as polytetrafluorethylene made for great dielectrics for such a button, while both human skin and latex surgical gloves are close to the top of the triboelectric series. It was revealed that buttons that had two dielectrics that are opposite to one another in the triboelectric series produced a very small amount of charge, and are thus unreliable. The intensity of charge on the person pressing the button was also thought to be major factor in determining the output voltage of the button. | ||||
