Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Open Circuit Solution for Pump Controlled Actuators
, 2006 Mobile machines of today often contain hydraulic valve controlled actuator loads in an open loop circuit. For the purpose of saving energy, the constant pressure pumps have in the past often been replaced by load sensing pumps and valves. In mobile applications, they have significantly reduced the energy consumption.

Pump-controlled hydraulic circuits for single-rod actuators: New designs and performance evaluation
, 2020 This thesis investigates the challenges in designing pump-controlled single-rod actuators and proposes new solutions for them. Three different concepts to overcome the reported performance problems are proposed. By applying the new concepts, eight different new designs are introduced, among which, five are experimentally evaluated.
