A Review of Smart Materials in Tactile Actuators for Information Delivery

, 2017
As the largest organ in the human body, the skin provides the important sensory channel for humans to receive external stimulations based on touch. By the information perceived through touch, people can feel and guess the properties of objects, like ...

Finite element analysis of shape-memory polymer mast

International Journal of Smart and Nano Materials, 2019
Space masts are widely used in the aerospace engineering as one type of deployable space structures. In this paper, based on the stimuli-responsive effects of shape-memory polymers (SMPs), an intelligent mast with shape-memory function is studied.

Kinetics of the helix-coil transition

, 2009
Based on the Zimm-Bragg model we study cooperative helix-coil transition driven by a finite-speed change of temperature. There is an asymmetry between the coil-to-helix and helix-to-coil transition: the latter is displayed already for finite speeds, and ...
