HTI Micro Actuators have Shape Memory Alloy (SMA) wires connected directly to a metal beam. The tiny SMA wire is used as the “motor” to move the metal beam. When electrical current is “ON”, the SMA wire heats up. The SMA wire shrinks when heated and pulls the free end of the beam up. When electrical current is “OFF”, the SMA wire cools. SMA wire can be stretched when cool and the beam goes flat. This SMA motor or combination of SMA motors can be configured into structures to provide 6 degrees of motion (X, Y, Z, pitch, yaw, & roll).
HTI Micro Actuators have key advantages in size, power, heat, performance, stability, magnetic interference, and environmental impact. HTI Micro Actuators’ unique designs enable small compact modules that have low power consumption which generates less heat allowing the module to deliver better performance. HTI Micro Actuators have no magnets and do not interfere with other devices like speakers and antennas. Additionally, HTI Micro Actuators do not contain any lead which is safer for the environment.
