a Photographs of oscillating film loaded with an object. b Displacement with different weight-lift ratios. c Work and power as a function of the weight-lift ratio upon infrared irradiation. d Photographs of film as a light motor. e Displacement, work, and power as a function of load. Error bars denote the standard deviation.
