Compliant displacement-multiplying apparatus for microelectromechanical systems

Patent Kota, Sridhar [9391 Quail Ridge Run, Brighton, MI 48114]; Rodgers, M Steven [12216 Papaya Ct., NE., Albuquerque, NM 87111]; Hetrick, Joel A [818 S. Gammon, Apartment 4, Madison, WI 53719]

A pivotless compliant structure is disclosed that can be used to increase the geometric advantage or mechanical advantage of a microelectromechanical (MEM) actuator such as an electrostatic comb actuator, a capacitive-plate electrostatic actuator, or a thermal actuator. The compliant structure, based on a combination of interconnected flexible beams and cross-beams formed of one or more layers of polysilicon or silicon nitride, can provide a geometric advantage of from about 5:1 to about 60:1 to multiply a 0.25-3 .mu.m displacement provided by a short-stroke actuator so that such an actuator can be used to generate a displacement stroke of about 10-34more »« less

Microelectromechanical systems contact stress sensor

Patent Kotovsky, Jack [Oakland, CA]

A microelectromechanical systems stress sensor comprising a microelectromechanical systems silicon body. A recess is formed in the silicon body. A silicon element extends into the recess. The silicon element has limited freedom of movement within the recess. An electrical circuit in the silicon element includes a piezoresistor material that allows for sensing changes in resistance that is proportional to bending of the silicon element.
