Abstract
A light-driven motor operated by a single source of light is demonstrated for the first time. The device utilizes a NiTi shape memory alloy (SMA) wire initially trained straight shape. The SMA wire was formed in a loop and put around two wheels. In the experiment a steady and continuous rotation was achieved with a bundled loop of 0.3-mm diameter wire. The rotational speed was proportional to the incident light power and 60 rpm was obtained at 3.6 W of light power. The experimental result was consistent with the theory.
