An ultrasonic sensor in a prosthesis allows amputees to control each of their prosthetic fingers individually.

Perking Up and Crimping the ‘Bristles’ of Polyelectrolyte Brushes

Polyelectrolyte brushes illustration: In the foreground, powerful ions in solution, shown as spheres, cause the brush's bristles to collapse like sticky spaghetti. In the background, gentler ions in solution cause the bristles to stand back straight. Credit: Peter Allen University of California Santa Barbara for this study
