N2 - New biomedical technological developments such as prosthetics and orthotics require a synergistic use of actuators, sensors, and microcontrollers. In order to obtain lighter machines, alternative actuators such as deformable micromotors and actuators are found. Shape Memory Alloys (SMA) are materials for which the Shape Memory Effect can be used to generate controlled displacements by inducing thermal variations through electric excitation signals. The Nickel Titanium SMAs have attracted scientific and technological attention for the development of flexible actuators. In particular, Nitinol is a material that can be trained in memory and form, reaching a large force while being light with a rapid mechanical response. This article presents a design and implementation methodology of Nitinol SMA-based actuators including a procedure of displacement characterization of the material, as well as the relations between thermal, mechanical and electric variables for a customized implementation. Graphical abstract: [Figure not available: see fulltext.].
