A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

The effect of viscoelasticity and tabletting speed on consolidation and relaxation of a viscoelastic material

European Journal of Pharmaceutics and Biopharmaceutics, 1996
This paper evalutes the applicability of Dynamic Mechanical Analysis (DMA) as a tool to explain consolidation and relaxation behaviour of a viscoelastic powder compressed at different speeds. From the DMA-data it is concluded that the material becomes more rigid and more elastic with increasing deformation rates. Compaction of the material at low speed
