Compliant Systems Overcome MEMS Challenges
Frictionless and assembly-free
compliant systems are a critical enabling technology for all
sorts of MEMS devices. While many MEMS devices use simple
cantilever beams to enable motion, FlexSys can design much
more sophisticated micro-systems that provide shape
change, efficient power transmission, complex motions, and
more.
Case Study - Compliant Electrostatic Actuator

A compliant electrostatic micro-actuator (structure in the lower left corner of the photo) is compared to the
original direct-drive electrostatic actuator (upper right). The compliant micro-
actuator produces four times more output force, generates the same output displacement,
and occupies one-fifth of the chip space - making it attractive for optical
switching and many other MEMS applications. (Photo courtesy of Sandia National Labs)

Case Study - Utra-Stiff Optical Switching Micro-Mirror

The photo to the right shows an
ultra-stiff optical switching micro-mirror that can be
precisely guided using high-force, short-stroke,
electrostatic actuators connected through
FlexSys-designed compliant displacement amplifiers to
produce precise, high-speed, tilt and roll
positioning. FlexSys has the knowledge-base and
computational tools to design sophisticated MEMS
mechanisms such as this. MEMX, a company that specializes
in the SUMMiT 5 level micro-fabrication processes
originally developed at Sandia National Labs, can make
these micro-designs a reality. (Photo courtesy of
