Publication number: 20220259038Abstract: A method for manufacturing a millimeter scale electromechanical device includes coupling a stainless steel ply to a polymer carrier ply, coating the stainless steel ply in a photo resist material, masking the photoresist material, exposing the photoresist material to cure a portion of the photoresist material, developing the photoresist material to remove uncured photoresist material from the stainless steel ply, chemically etching the stainless steel ply to remove a patterned portion of the stainless steel ply, dissolving the polymer carrier ply to release unwanted chips of the stainless steel ply, and adhering the patterned stainless steel ply to a flexible material ply to form a sub-laminate.Type: ApplicationFiled: May 9, 2022Publication date: August 18, 2022Applicant: VIBRANT COMPOSITES INC.Inventors: Pratheev S. SREETHARAN, Andrew Baisch, Alina Visco, Michael Karpelson

Publication number: 20220184662Abstract: A haptic actuator includes mechanical links defining a first J-trajectory and mechanical links defining a second J-trajectory as well as a motor coupled to the mechanical links so as to synchronously accelerate a first mass over the first J-trajectory and a second mass over the second J-trajectory. During a first time interval, reactive forces of the first mass accelerating substantially balance reactive forces of the second mass accelerating and during a second time interval reactive forces of the first mass accelerating do not substantially balance reactive forces of the second mass accelerating. This un-balanced condition results in a tap signal being produced.Type: ApplicationFiled: February 5, 2022Publication date: June 16, 2022Applicant: Vibrant Composites Inc.Inventors: Pratheev S. SREETHARAN, Michael Karpelson
