Graphene Based Triboelectric Nanogenerators Using Water Based Solution Process

A rapid development in personal electronics has raised challenging requirements for portable and sustainable power sources. For example, wearable technologies, the concept of body area network brings motion vital signs monitoring together synergy. this, a key aspect is energy, available anywhere, at any time, as generated by triboelectric nanogenerators (TENG). This technology usually demands high-cost processes materials still suffer from low output, well unstable output values due to charge generating stimulus with variable intensities. In this work, we present TENGs using shear exfoliated graphene electrodes active layer deposited simple solution process. Graphene combination polymers such polydimethylsiloxane (PDMS) were used produce TENG devices low-cost processing methods. Device electrical generation was tested cyclic physical better control understanding device output. The response these showed open circuit voltages (V oc ) short-circuit currents (I sc )of approximately 233 V 731 nA respectively when stimulated 1.5 Hz. density 13.14 ?W/cm 2 under load 200 M? achieved, which can be 40 times higher compared made aluminum PDMS. These results demonstrate potential process self-sustainable on health security applications contact positional sensors.
