Patent number: 10843336Abstract: Reconfigurable soft robotic actuators with hard components are described. Magnetic attraction is used to couple flexible molded bodies capable of actuation upon pressurization with other flexible molded bodies and/or with hard components (e.g., frames and connectors) to form a seal for fluidic communication and cooperative actuation. Pneumatic de-coupling chambers built into the hard components to de-couple the hard components from the magnetically-coupled soft molded bodies are described. The use of magnetic self-alignment coupling and pneumatic de-coupling allows for the remote assembly and disassembly of complex structures involving hard and soft components. The magnetic coupling allows for rapid, reversible reconfiguration of hybrid soft-hard robots for repair, testing new designs, and carrying out new tasks.Type: GrantFiled: May 8, 2018Date of Patent: November 24, 2020Assignee: President and Fellows of Harvard CollegeInventors: Sen Wai Kwok, Stephen A. Morin, Bobak Mosadegh, Ju-Hee So, Robert F. Shepherd, George M. Whitesides

Publication number: 20200178388Abstract: Disclosed are a fiber composite laminate including a self-assembled conductive paste and a method of manufacturing the same. The fiber composite laminate includes a fiber-based circuit unit including a fiber substrate and a circuit electrode positioned on the fiber substrate, a composite binder unit positioned on the fiber-based circuit unit, and a connection unit including a connection electrode positioned on the composite binder unit and a flexible substrate positioned on the composite binder unit and the connection electrode. The fiber composite laminate can thus be applied to wearable devices having increased conductivity and durability of joints thereof, a minimized foreign-body sensation, and an improved wearing sensation. Moreover, productivity can be increased owing to a simple manufacturing process, and mass production becomes possible.Type: ApplicationFiled: November 29, 2019Publication date: June 4, 2020Applicant: KOREA INSTITUTE OF INDUSTRIAL TECHNOLOGYInventors: Eui Sang YOO, Hyun Kyung LEE, Eunjoo KIM, Jung Hun LEE, Soo Hyeon RHO, Dae Young LIM, Ju Hee SO
