For converting light energy into electricity, an Optical pendulum generator was designed by combining photomechanical movement of liquid-crystalline actuator (LCA) with Faraday's law of electromagnetic induction. Bilayer cantilever actuators were first fabricated with LDPE and LCA. Their photomechanical movement drove the attached copper coils to cut magnetic line of force generating electricity. The output electricity was proportional to the changing rate of the Magnetic flux, which was greatly influenced by light intensity, film thickness, and sample size. Continuous electrical output was also achieved: This simple strategy may expand applications of photoactive materials in the capture and storage of light energy.
