Abstract

Magnetic-energy harvesting in a centimeter-sized free-standing (BEDT-TTF)C<sub>60</sub> charge-transfer single crystal is demonstrated. The crystal shows sensitive magnetic-, thermal-, and mechanical-sensing ability, with an excellent piezoresistance coefficient of -5.1 × 10<sup>-6</sup> Pa<sup>-1</sup> . The self-powered sensing performance, together with its solution processability and flexibility, endow it with the capability of driving a new generation of noncontact magnetic-energy harvesting and sensing technologies.
