This New Device Can Generate Electricity from Human Motion

You may never need to carry a charger again, instead, your phone will draw energy from your clothes and the environment. This is the potential of a new device developed at Vanderbilt University’s Nanomaterials and Energy Devices Laboratory.

Using battery technology and layers of black phosphorus, the new device generates small amounts of electricity when bent or pressed. The phosphorus which is only a few atoms thick can generate the electricity even at extremely low frequencies in line with human movement.

Assistant Professor of Mechanical Engineering, Cary Pint, who directed the research said, “In the future, I expect that we will all become charging depots for our personal devices by pulling energy directly from our motions and the environment.”

The findings were published in a paper titled, “Ultralow Frequency Electrochemical Mechanical Strain Energy Harvester using 2D Black Phosphorus Nanosheets”  in the online journal ACS Energy Letters.
