TL;DR: A microfluidic tactile diaphragm pressure sensor based on embedded Galinstan microchannels capable of resolving sub-50 Pa changes in pressure with sub-100 Pa detection limits and a response time of 90 ms is demonstrated.
Proceedings ArticleDOI
An electrostatic gripper for flexible objects
TL;DR: A flexible, electrostatic adhesive gripper designed to controllably grasp and manipulate soft goods in space and mounted on a 7-DoF robot arm and performed a supervised grasp, manipulate, and release sequence on a hanging, Al-coated PET film.
Journal ArticleDOI

Duncan W. Haldane,Carlos S. Casarez,Jaakko T. Karras,Jessica P. Lee,Chen Li,Andrew Pullin,Ethan W. Schaler,Dongwon Yun,Hiroki Ota,Ali Javey,Ronald S. Fearing +10 more
TL;DR: Haldane et al. as discussed by the authors developed a number of manufacturing methods for the fabrication of structures for attachment, protection, and sensing based on infrared laser machining of lamina and the bonding of layered structures.
Journal ArticleDOI
Thin-film repulsive-force electrostatic actuators
TL;DR: In this article, thin-film repulsive-force electrostatic actuators with a new electrode pattern and a planar, flex-circuit manufacturing process are used for low-force actuation applications.
