Use of Sand-polished Kapton Film and Aluminum as Source of Electron Transfer Triboelectric Nanogenerator through Vertical Contact Separation Mode: An Overview| Chapter 8 | Current Approaches in Engineering Research and Technology Vol. 6

Recently, triboelectric nanogenerators (TENGs) have received worldwide attention for the harvesting of sustainable green energy from ambient resources. TENGs are developed based on a combination of contact separation mode electrification and electrostatic induction to scavenge reduced mechanical energy using triboelectric materials. Contact electrification is a direct triboelectrification method for producing current through charge transfer when two different differentiated materials are brought into contact. For the first time, we developed a simple TENG where the electronic charges were realized through contact separation mode between sand-polished Kapton (SPK) and Al surface. Here, we demonstrated the energetic interfacial contact between these surfaces and observed satisfactory output performance. The examination of the electric output of SPK-Al TENG upon connecting directly to an external load at different resistors. Based on the experimental results, the change in impact force was gradually increased with respect to the applied contact frequencies. The novel SPK-TENG produced 40 V and 2.8

A, of open-circuit voltages (Voc) and short-circuit currents (Isc) at 4 Hz, respectively. Mainly, the SPK-TENG has dramatically increased the performance of TENG, up to 40% of Voc and 42% of Isc, with respect to the Kapton film because the mobility of electrons is very high on the device surface compared to the other pristine Kapton film. The fabricated SPK-TENGs were good candidates for satisfying the need for alternative contact separation mode TENGs.
