Abstract The use of ‘Electrostatic tweezers’ is a promising tool for droplet manipulation, but it faces many limitations in manipulating droplets on superhydrophobic surfaces. Here, we achieve noncontact and multifunctional manipulation Nepenthes-inspired lubricated slippery surfaces via triboelectric electrostatic tweezers (TETs). TET surface has advantages over surface. field induces the redistribution charges inside neutral droplet, which causes charged rod to drive move forward under force. Positively or negatively can also be driven by based attraction repulsion. enables us manipulate diverse conditions, including anti-gravity climb, suspended droplets, corrosive liquids, low-surface-tension liquids (e.g. ethanol with tension 22.3 mN·m −1 ), different volumes (from 100 nl 0.5 ml), passing through narrow slits, sliding damaged areas, various solid substrates, even an enclosed system. Various droplet-related applications, such as motion guidance, switching, droplet-based microreactions, cleaning, defogging, liquid sorting, cell labeling, easily achieved TETs.
