a The experimental setup for manipulating and imaging the micro-actuators on a chip. The scanning galvo system is the key component for generating programmable, arbitrary laser trajectories to optically drive the actuator. BS: beam splitter, CCD: charge-coupled device. b Schematic illustration of the actuator’s movements due to the scanning laser beam, showing the assembling of the letter “U" after an actuator has moved in a straight line, turned around, and crossed a waveguide. The white dashed curve represents the movement trajectory of the actuator. c Molecular structure of the micro-actuator. d SEM image of a typical micro-actuator on a glass substrate, with the length and width being 9.7 μm and 1.2 μm, respectively. Scale bar: 2 μm. e Measurement of the micro-actuator’s displacement as a function of laser power, revealing a threshold behavior.
