In this paper two assistive orthoses which use different types of actuation mechanisms are presented and discussed.
In addition, since this new type of actuator demonstrates optical property changing together with actuation process, which is smarter compared to previous conventional actuators, a smart window is fabricated, indicating its application in personal privacy protection and intelligent household devices.
Inerters are a novel type of mechanical actuation devices that are able to produce large inertial forces with a relatively small mass.
The design procedure presented here can handle systems with an arbitrary finite number of open-loop unstable eigenvalues and is not restricted to a particular type of boundary actuation.
Fig. 3 Different types of magnetic actuation.
Two different types of surface actuation are considered––tangential blowing and suction through a single slot.
To avoid an additional actuator for this adjustment, a bi-stable mechanism was implemented which changes the actuation type of the differential from a point force in the compliant state to an antagonistic couple in the stiff state once the actuator force overcomes a threshold value.
A photostrictive type of opto-electromechanical actuator activated by high-energy lights can introduce actuation and control effects without hard-wired connections.
The high requirements of micro-chemical mixing, biological detection and insulin injection raises new actuation requirements in the diversity of actuation functions and types [1, 2, 3, 4, 5, 6, 7], and the conventional actuators cannot fulfil these requirements efficiently [8, 9, 10, 11].
