Abstract
The rise in significance of wearable actuators can be attributed to their capability to offer real-time tactile feedback, multi-functionality, and above all, optimal comfort to users. While various actuator types like motor-driven tendons, pneumatics, and electromagnetics have been utilized in wearable applications, they often entail the addition of a cumbersome rigid system to the wearer, potentially leading to discomfort. Shape memory alloys (SMAs), which alter their physical form and rigidity based on temperature variance, present a viable option for wearable actuators, particularly when processed into fabric form using SMA wires. In this study, we developed an SMA-based fabric type actuator by intricately knotting SMA wires and subsequently expanding them into 2D textile form. Further, the auxetic meta-design is introduced, enhancing its adaptability to the 3D contours of human body. This auxetic-architectured SMA fabric was effectively employed as a wearable haptic device, conveying spatiotemporal feedbacks to users.
