what is a
microhydraulic
actuator?
A microhydraulic actuator harnesses the forces created when an electric field distorts the surface tension of microscopic drops of oil.
More detailed explanation
Invented at the MIT Lincoln labs, Sangtera’s microhydraulic actuators harness the power of electrowetting to address all the constraints faced by conventional electromagnetic systems.
400x increase in torque-density
Our microhydraulic actuators generate four hundred times the torque generated by a conventional motor of the same mass.
Excellent force feedback
With high torque density, we eliminate the need for a high gear ratio. This makes Sangtera actuators inherently backdrivable — they can sense and respond to forces from the environments, without the need for additional sensors.
Zero-power hold
Since our microhydraulic actuators harness electrostatic forces, once they reach a particular shape, they can hold that shape even if the power supply is cut off.
