Abstract
This study investigates a simple, yet effective and affordable, manufacturing method to increase the electrical efficiency by triboelectric generator (TEG) applying 3D printers. In this study, we propose the newly manufacturing method for producing a macroscale surface patterning. Overall experiments were conducted in designed test-bed chamber system which can control the magnitude and frequency of the frictional force and the relative humidity. Furthermore, we can demonstrate the voltage enhancement of macroscale surface patterns about 1.6-fold. The peak voltage producing by TEG was as high as 18 V. In comparison with conventional process that employ micro- and nanoscale patterns, the proposed process by 3D printer is faster and more suitable for mass production.
