Method and device for reversibly attaching a phase changing metal to an object
US Patent Application 10675718, January 2020 (patent)
A method for reversibly attaching a phase changing metal to an object, the method comprising the steps of:
providing a substrate having at least one surface at which the phase changing metal is attached,
heating the phase changing metal above a phase changing temperature at which the phase changing metal changes its phase from solid to liquid,
bringing the phase changing metal, when the phase changing metal is in the liquid phase or before the phase changing metal is brought into the liquid phase, into contact with the object,
permitting the phase changing metal to cool below the phase changing temperature, whereby the phase changing metal becomes solid and the object and the phase changing metal become attached to each other,
reheating the phase changing metal above the phase changing temperature to liquefy the phase changing metal, and
removing the substrate from the object, with the phase changing metal separating from the object and remaining with the substrate.

US Patent 9,731,422, 2017 (patent)
The present invention are methods for fabrication of micro- and/or nano-scale adhesive fibers and their use for movement and manipulation of objects. Further disclosed is a method of manipulating a part by providing a manipulation device with a plurality of fibers, where each fiber has a tip with a flat surface that is parallel to a backing layer, contacting the flat surfaces on an object, moving the object to a new location, then disengaging the tips from the object.

Remotely addressable magnetic composite micro-actuators
Sitti, M., Diller, E., Miyashita, S.
February 2016, US Patent 9,281,112 (patent)
The present invention describes methods to fabricate actuators that can be remotely controlled in an addressable manner, and methods to provide remote control such micro-actuators. The actuators are composites of two permanent magnet materials, one of which is has high coercivity, and the other of which switches magnetization direction by applied fields. By switching the second material's magnetization direction, the two magnets either work together or cancel each other, resulting in distinct “on” and “off” behavior of the devices. The device can be switched “on” or “off” remotely using a field pulse of short duration.

Methods of forming dry adhesive structures
Sitti, M., Murphy, M., Aksak, B.
September 2015, US Patent 9,120,953 (patent)
Methods of forming dry adhesives including a method of making a dry adhesive including applying a liquid polymer to the second end of the stem, molding the liquid polymer on the stem in a mold, wherein the mold includes a recess having a cross-sectional area that is less than a cross-sectional area of the second end of the stem, curing the liquid polymer in the mold to form a tip at the second end of the stem, wherein the tip includes a second layer stem; corresponding to the recess in the mold, and removing the tip from the mold after the liquid polymer cures.
