Tris(2-carboxyethy1)phosphine (TCEP) reduces disulfides rapidly and completely in water at pH 4.5. It preferentially reduces more strained disulfides, in accordance with the usual mechanism postulated for reduction of disulfides by phosphines in water. The reagent can be synthesized conveniently in large quantities by acidic hydrolysis of the commercially(More)
We wish to develop robot systems that are increasingly more elastic, as a step towards bridging the gap between man-made machines and their biological counterparts. To this end, we develop soft actuators fabricated from elastomer films with embedded fluidic channels. These actuators offer safety and adaptability and may potentially be utilized in robotics,(More)
comprised of elastomeric materials with integrated channels that function as pneumatic networks (PneuNets), are designed and geometrically analyzed to produce bending motions that can safely conform with the human finger motion. Bending curvature and force response of these actuators are investigated using geometrical analysis and a finite element model(More)
A pneumatically-driven robot traverses surfaces with different traction by adopting an undulatory mode of locomotion. The robot is composed of soft elastomer (elastic modulus ∼100 kPa), an inextensible but flexible neutral plane, and embedded pneumatic channels. In contrast to conventional robots and wheeled vehicles, the robot deforms elastically to make(More)
