Advanced Materials Technologies, Volume 9, Issue 14, July 22, 2024.High force electroadhesive clutch enabled by considering fracture mechanics and using BaTiO3/P(VDF‐TrFE‐CTFE)‐based dielectric coating shows high EA shear stress up to 108 N cm−2 at 300 V. This also enables low voltage operations of a wide range of applications and miniaturization of devices while providing the sufficient EA force.

Magnetorheological brake modeling with machine learning
, 2020 Precise control of the braking torque of an MR-brake (MRB) is possible with a control system using a Hall sensor which measures the magnetic field. Closed-loop controllers can be used to control the torque based on the Hall sensor readings. However, over time the fluid slowly leaks out of the MRB due to failure of rubber seals, which degrades the ...
