design a chip for flexible multifunction optical micro-manipulation based on elastomeric materials-pdms. we realized the different motion types of microspheres, including stably capture, spiral motion and orbital rotation, by adjusting the input voltage of piezoceramics designed in pdms chip. compared to conventional techniques, this pdms chip based method does not require special optical properties of the microspheres to be manipulated. in addition, the technique was convenient and precise for dynamical adjustment of motion types without external influences. from these results, we verify that this multifunctional optical micro-manipulation technique of pdms elastomeric materials can find potential applications for optical manipulation, including cost-effective on-chip diagnostics, optical sorting and optical binding, etc. © 2017 spie.
