A Smart Mobile Pouch Triboelectric Nanogenerator (SMP-TENG) is introduced as a promising eco-friendly
approach for scavenging biomechanical energy for powering next generation intelligent devices and
smart phones. This is a cost-effective and robust method for harvesting energy from human motion,
by utilizing worn fabrics as a contact material. The SMP-TENG is capable of harvesting energy in two
operational modes: lateral sliding and vertical contact and separation. Moreover, the SMP-TENG can also
act as a self-powered emergency flashlight and self-powered pedometer during normal human motion.
A wireless power transmission setup integrated with SMP-TENG is demonstrated. This upgrades the
traditional energy harvesting device into a self-powered wireless power transfer SMP-TENG. The wirelessly
transferred power can be used to charge a Li-ion battery and light LEDs. The SMP-TENG opens a
wide range of opportunities in the field of self-powered devices and low maintenance energy harvesting
systems for portable and wearable electronic gadgets.
