SMA microgripper system

Sensors and Actuators A: Physical, 2001
A microgripper system is presented, which consists of a monolithic shape memory alloy (SMA) device of 2 × 5.8 × 0.23 mm3 size and an integrated optical position sensor. By use of an integrated gear actuator, the motion of gripping jaws is transmitted into a linear motion of an integrated optical slit, which is detected by change of optical transmission.

Design and Implementation of a Soft Robotic Arm Driven by SMA Coils

IEEE transactions on industrial electronics (1982. Print), 2019
Soft robots may potentially be used for human services and complex environmental locomotion. The bodies of the soft robots are made from soft materials to make them safe for human interactions and to enable them to deform enough to adapt to soft or rough

SMAS-Platysma Face Lift

Plastic and Reconstructive Surgery, 1983
Correction of laxity in the submental area and of hypertrophic neck cords has been enhanced with the SMAS-platysma face life over that which was achieved with a standard skin face lift. Evaluation of a 6-year experience with the SMAS-platysma face lift reveals that the operation can be safely performed with an acceptably low incidence of complications.

Discrepancy in redetermination of SMN2 copy numbers in children with SMA

Neurology, 2019
Spinal muscular atrophy (SMA) is a rare autosomal recessive inherited neuromuscular disease with an incidence of about 1:6,000 to 1:10,000 in newborns. The clinical spectrum of severity is broad and ranges from early and severe weakness with respiratory ...

Improving the seismic performance of post-tensioned self-centering connections using SMA angles or end plates with SMA bolts

Smart materials and structures (Print), 2019
Cyclic performance of self-centering post-tensioned (PT) steel beam-column connections has been investigated numerically by introducing stiffened angle connection, shape memory alloy (SMA) angle connection and SMA bolted end plate connection.
