Patent number: 10570005Abstract: The disclosure provides methods and apparatus for release-assisted microcontact printing of MEMS. Specifically, the principles disclosed herein enable patterning diaphragms and conductive membranes on a substrate having articulations of desired shapes and sizes. Such diaphragms deflect under applied pressure or force (e.g., electrostatic, electromagnetic, acoustic, pneumatic, mechanical, etc.) generating a responsive signal. Alternatively, the diaphragm can be made to deflect in response to an external bias to measure the external bias/phenomenon. The disclosed principles enable transferring diaphragms and/or thin membranes without rupturing.Type: GrantFiled: September 5, 2012Date of Patent: February 25, 2020Assignee: Massachusetts Institute of TechnologyInventors: Apoorva Murarka, Vladimir Bulovic, Sarah Paydavosi

Patent number: 9419147Abstract: A method and apparatus for making analog and digital electronics which includes a composite including a squishable material doped with conductive particles. A microelectromechanical systems (MEMS) device has a channel made from the composite, where the channel forms a primary conduction path for the device. Upon applied voltage, capacitive actuators squeeze the composite, causing it to become conductive. The squishable device includes a control electrode, and a composite electrically and mechanically connected to two terminal electrodes. By applying a voltage to the control electrode relative to a first terminal electrode, an electric field is developed between the control electrode and the first terminal electrode. This electric field results in an attractive force between the control electrode and the first terminal electrode, which compresses the composite and enables electric control of the electron conduction from the first terminal electrode through the channel to the second terminal electrode.Type: GrantFiled: January 9, 2015Date of Patent: August 16, 2016Assignee: Massachusetts Institute of TechnologyInventors: Vladimir Bulovic, Jeffrey H. Lang, Sarah Paydavosi, Annie I-Jen Wang, Trisha L. Andrew, Apoorva Murarka, Farnaz Niroui, Frank Yaul, Jeffrey C. Grossman
