The Application Potentials of Shape Memory Alloys in Hand Tools

Shape memory alloys show remarkable potentials as actuators and elastic elements. Due to their compact design smallest actuators with multifunctional properties can be implemented in small installation space, even in hand tools. The publication focuses on a comparison between technical SMA specifications and future perspectives regarding hand tools and portable automated tool systems. Within this publication two examples of innovative systems are discussed: A haptic information feedback system based on SMA wires implemented in handles for communication between user and tool is presented as well as an automated installation ring opener.
