This paper presents a proof-of-concept study of a novel active hinge that has the potential application into solar panels for providing the panels with not only self-deploying/folding functions but also active vibration control capacity. The hinge is conceived with a compact structure mainly integrated with an electro-permanent-magnet driving mechanism and a magnetostricve-piezoelectric effect (ME) sensor. In current research stage, a prototype of the driving mechanism and a ME sensor were built. The behavior of the driving mechanism and the capacity of the ME sensor were experimentally tested, separately. The panel can be directly driven to deploy/fold for 180 degree only through a half-sinusoidal signal in two pairs of coils, and its capacity of vibration attenuation was also confirmed by an active open-loop control test. Meanwhile, the ME sensor was preliminary tested for a capacity of 360 degree rotation measurement with 0.01 degree resolution. The self-sensing drive function that the driving mechanism integrated with the ME sensor is going to finish in the coming research.
