| Abstract | ||||
| Triboelectric nanogenerators (TENGs) have emerged as a possible solution to many problems of our modern world by satisfying the need for self-powered sensors and new methods of energy harvesting. One of the applications of TENGs as self-powered sensors is as pressure sensors. This can be done by making a TENG with only one electrode connected to a dielectric. This paper proposes a method of using TENG-based Kapton pressure sensors in order to make a self-powered chess board with move recognition capabilities. It was found that the voltage generated by the sensor at contact increased with increasing the placing force of a wooden cube (simulating a chess piece) on it. However, the voltage generated at separation did not increase with the placing force. It was also found that voltage always increased with the resistance between the electrode and the ground in a resistance range of 0.33 MΩ to 50 MΩ. Current usually increased with resistance at first then stabilized at some point. A chess board column was then created using 8 pressure sensors connected to each other via resistances. It was found that the voltage between the chess board column and the ground decreased as the square number on which the wooden cube was placed or removed from increased. Showing that this is a viable method of monitoring movements across this column. | ||||
