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 has key advantages in size, power, heat, performance, stability, no magnetic interference, and is lead-free. HTI Micro Actuator’s unique design enables a small compact module that has low power consumption which generates less heat allowing the module to operate at a lower temperature and deliver better performance. Since HTI Micro Actuator uses no magnets, it does not interfere with other devices like speakers and antennas.
