A device made with sheets of black phosphorus, a two-dimensional semiconducting material, can generate electricity when it is bent or pressed at ultralow frequencies (ACS Energy Lett.2017, DOI: 10.1021/acsenergylett.7b00478). Incorporated into clothing, the paperthin device could produce electricity by harnessing relatively slow motions like walking, bending, or standing up.
