Bistabiles Magneto-Formgedächtnis-Mikroventil

Bistable actuators only consume energy during the switching process. This characteristic renders these kind of actuators extremely interesting for applications in the field of microfluidics. This work presents a novel principle of bistable actuation, which combines an antagonistic shape memory alloy (SMA) actuation mechanism with magnetostatic latching. A bistable microvalve, using this principle is demonstrated.
