Providing information to those who are blind or have low vision is critical for enhancing mobility, situational awareness, education, and more. Tactile information delivery can be effective, rapid, and private. Examples include refreshable Braille and text based tactile displays, both of which convey text to the user through either quasistatic or vibratory motion of piezoelectric bending beam actuators. However, not all information can be conveyed easily in text format. Graphical information that sighted people would perceive visually (e.g. scientific diagrams) can best be expressed to those with visual impairment through tactile graphics. Existing technologies of tactile actuators lack the necessary combination of compact size, large displacement and force, portability and cost effectiveness.

520 $a Providing information to those who are blind or have low vision is critical for enhancing mobility, situational awareness, education, and more. Tactile information delivery can be effective, rapid, and private. Examples include refreshable Braille and text based tactile displays, both of which convey text to the user through either quasistatic or vibratory motion of piezoelectric bending beam actuators. However, not all information can be conveyed easily in text format. Graphical information that sighted people would perceive visually (e.g. scientific diagrams) can best be expressed to those with visual impairment through tactile graphics. Existing technologies of tactile actuators lack the necessary combination of compact size, large displacement and force, portability and cost effectiveness.
520 $a In this work, a new type of tactile actuator is designed, modeled, implemented, and characterized. The technologies needed to create these actuators are created as well. In these actuators, the small, in-plane motions from an extensional actuator are converted and amplified by a scissor mechanism into larger, out-of-plane motions that are suitable for tactile sensing by human finger pads. These actuators offer the possibility of providing large displacement and high force from a limited device area that is comparable to the resolution of human finger pads. The design, fabrication and characterization of several technology generations of MEMS-enabled, vibrational tactile actuators are presented. In the first generation, flexural hinges created by additive manufacturing and in photodefinable epoxy are used to implement the jointed scissor architecture. In the second generation, a down-scaled architecture is created by implementing flexural hinges in a more compact geometry and a laminated architecture. In the third and fourth generations of the device design, the jointed architecture is implemented using two-part, concentric hinges that undergo free rotation within a given rotational range. These technologies enable the creation of tactile actuators down to the size scale of 2 mm2 area. The resulting tactile actuators deliver force per-unit-area of greater than 2.5 mN/mm2 and displacement per-unit-area of greater than 1.5 mum/mm 2. Human sensing perception testing was also conducted, demonstrating successful tactile actuation function. These actuators have potential in applications like virtual reality sensory feedback, private communications and microrobotics.
