This paper presents an innovative approach to creating Shape Memory Alloys (SMA)-based actuators that are lightweight, compact, and capable of providing large strokes. Inspired by the Kirigami structure, an SMA actuator is designed using the Ω -pattern, wh ...

The need for the gripper becomes more demanding when it comes to automated manipulation or handling of fragile structures. Depending on the object and the task requirements, a single gripper with a fixed stiffness may not be enough, and a variable mechanis ...

Including friction modeling in simulation can be challenging and requires time domain simulation, which is time consuming. We propose to separate the friction modelling from the FEA (Finite Element Analysis). The approach is defined for UCM (Ultrasonic Cer ...

Shape Memory Alloys (SMAs) have gained significant attention due to their high work density in order to fabricate compact and lightweight actuators. However, the major drawback of thermally activated SMAs is the time that takes for these materials to cool ...

In this paper, we investigate a novel passive approach to improve the actuation frequency of Shape Memory Alloys (SMAs) with the Kirigami-inspired design using a thin layer of highly thermally conductive material. By depositing an 80 nm layer of gold on th ...

Using shape memory alloys (SMAs) as actuators offers several advantages, including high power density, large stroke capabilities, and friction elimination. These attributes make SMAs suitable for actuating flexure-based mechanisms in a wide array of extrem ...
