摘要： 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.

摘要： 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.
