Frictionless drive system achieves stable nanometer positioning precision over an unprecedented distance

Filling a major gap in precision control for applications from semiconductor fabrication to manipulations of living cells, A*STAR researchers have developed a frictionless drive system that provides nanometer precision over millimeters of travel without complicated feedback control1. The system, developed by Daniel Tat Joo Teo and colleagues from the A*STAR Singapore Institute of Manufacturing Technology, has the potential to revolutionize experimentation and fabrication at the nanoscale.
