• The robot that grips without touching
    ETH Pioneer Fellow Marcel Schuck is developing a robotic gripper that can manipulate small and fragile objects without touching them. The technology is based on sound waves.he small installation that Marcel Schuck has assembled on his workbench is reminiscent of a school physics lesson: an arrangement, compri......

  • A transparent, self-healing and high-κ dielectric for low-field-emission stretchable optoelectronics
    Stretchable optoelectronic materials are essential for applications in wearable electronics, human–machine interfaces and soft robots. However, intrinsically stretchable optoelectronic devices such as light-emitting capacitors usually require high driving alternating voltages and excitation frequencies to ac......

  • Thermoplastic moulding of regenerated silk
    Early insights into the unique structure and properties of native silk suggested that β-sheet nanocrystallites in silk would degrade prior to melting when subjected to thermal processing. Since then, canonical approaches for fabricating silk-based materials typically involve solution-derived processing metho......

  • Fast Digital Patterning of Surface Topography toward Three-Dimensional Shape-Changing Structures
    Exiting strategies for 3D shape-changing structures are constrained by either the complicated fabrication process or the harsh demands of active materials. Facile preparation of 3D shape-changing structures with an extremely simple approach based on the elastomeric polymer still remains a challenging topic. H......

  • Probing Contact-Electrification-Induced Electron and Ion Transfers at a Liquid–Solid Interface
    As a well-known phenomenon, contact electrification (CE) has been studied for decades. Although recent studies have proven that CE between two solids is primarily due to electron transfer, the mechanism for CE between liquid and solid remains controversial. The CE process between different liquids and polytetrafluor......

  • Acoustic Holographic Cell Patterning in a Biocompatible Hydrogel
    Acoustophoresis is promising as a rapid, biocompatible, noncontact cell manipulation method, where cells are arranged along the nodes or antinodes of the acoustic field. Typically, the acoustic field is formed in a resonator, which results in highly symmetric regular patterns. However, arbitrary, nonsymmetrically sh......
