Description: This project will field-test the in-house developed triboelectric nanogenerator (TENG) that can harvest energy from the wind and all kinds of vibrations and motions. A TENG is an energy-harvesting device that converts the external mechanical energy (such as wind and any other motion/vibration) into electricity by a conjunction of triboelectric effect and electrostatic induction through rubbing two sheets of materials. The TENG is an extremely lightweight alternative to conventional (but heavy) electromagnetic motors and ideally suited for Mars exploration due to its launching and propulsion cost advantages. Problem Statement A potential is created by the triboelectric effect due to the charge transfer between two thin organic/inorganic films that exhibit opposite tribo-polarity. Electrons are driven to flow between two electrodes attached on the backsides of the films in order to balance the potential. The amount of energy generated depends on the source and can range from mW and MW. Technology Maturation The goal of using TENG on Mars one day for wind power generation has to overcome several known and unknown technical challenges, and the next step in the process is a realistic test bed in a balloon flight. The Martian surface wind can be emulated at 15-18km altitude on earth. The balloon flight can simultaneously demonstrate the commercial benefits for the high-altitude wind energy.

Benefits: Energy harvester that convers mechanical energy such as wind into electricity by collecting triboelectrostatic charges generated through rubbing two sheets of material of opposite polarities. Offers good weight-power density as it utilizes a friction force between paper-thin polymer sheet and metal foil.
