Some New Concepts of Shape Memory Effect of Polymers [PDF]

, 2014
In this study some new concepts regarding certain aspects related to shape memory polymers are presented. A blend of polylactic acid (PLA) (80%) and polybutylene succinate (PBS) (20%) was prepared first by extrusion, then by injection molding to obtain ...

A method to determine the accuracy of shape setting thin, spirally shaped Nitinol wires

Current Directions in Biomedical Engineering, 2021
Electric stimulation of the auditory nerve using a cochlear implant (CI) is presumed to be superior when the electrode array (EA) is placed close to the inner wall of the cochlea. Nitinol is investigated as an actuator that enables an intracochlear shape
