Triboelectric electrostatic tweezer (TET) manipulating droplets on the femtosecond laser-structured slippery surfaces (IMAGE)

The electrostatic rod can change the motion path of the free-falling raindrop, causing the raindrop to be either attracted or repelled away. These phenomena prove that electrostatic fields are a potential means to remotely manipulate droplets. The Nepenthes-inspired lubricated slippery surfaces have extremely low adhesion to droplets, allowing droplets to slide easily on the slippery surfaces. In combination with the electrostatic interaction and the femtosecond laser-designed slippery surfaces, a technology called “triboelectric electrostatic tweezer (TET)” was developed to achieve noncontact and multifunctional droplet manipulation. This technology will lead to exciting applications ranging from biological analysis to chemical manufacturing and from microfluidics to intelligent printing.
