Claim 0:
1. A microelectromechanical systems (MEMS) device, comprising:
a first arm having a first arm first end and a first arm second end;
a second arm coupled to, and spaced apart from, the first arm, the second arm having a second arm first end and a second arm second end;
at least one permanent magnet coupled to the first arm second end;
a fan structure coupled to, and extending in cantilever manner from, the second arm second end, the fan structure comprising a connection end and a free end, the connection end coupled to the second arm second end, the free end spaced apart from the at least one permanent magnet; and
a coil disposed on or within the fan structure at a location that is at least adjacent the free end,
wherein, when the coil is electrically energized, a Lorentz force is generated that causes the fan structure to vibrate relative to the at least one permanent magnet.
