“…The UltraShiver consists of two piezoelectric actuators glued symmetrically on opposite sides of a sheet of anodized aluminum [11]. Forces are produced by synchronizing in-plane ultrasonic oscillation and out-of-plane electroadhesion.…”

“…The former is tuned to the first longitudinal resonance of the UltraShiver. Even though the device shows good ability to control the lateral force, render convincing haptic effects, and localize them [6,11], it cannot provide a consistent magnitude of the lateral force over a large area due to the mode shape. The lateral force decreases to zero as the finger moves toward the nodal line, which is close to the center of the surface.…”

“…A detailed model of force generation with the UltraShiver is given in [11]. The SwitchPaD produces lateral force in the same way: as a result of friction being greater when electroadhesion is turned high than when it is turned low, and this effect being synchronized with in-plane oscillation.…”

“…The UltraShiver, for the first time, combined piezoelectric excitation of an ultrasonic resonance with electroadhesion to achieve both high forces and silent operation [11], but provided only a small touch area. This paper proposes a new haptic device, the SwitchPaD, that can achieve active lateral forces (±250mN) over a large area and in the inaudible region.…”

We present a new device, the SwitchPaD, to generate an active lateral force on a bare fingertip over a large touch area. Like our previous device, the UltraShiver, the SwitchPaD uses synchronization of in-plane ultrasonic oscillation and out-of-plane electroadhesion to generate force. The UltraShiver, however, relied on a single longitudinal resonance to produce oscillations, resulting in an inconsistent force profile. The SwitchPaD switches between the first and the second longitudinal mode based on the finger position, resulting in a much more consistent force profile across the touch surface. Experiments are used to compare the performance of two different modal switching strategies. Results indicate that the SwitchPaD can generate 250 mN peak active lateral force over a large area, and that, with the proper switching strategy, the switch itself is imperceptible.

Since the modern concepts for virtual and augmented reality are first introduced in the 1960's, the field has strived to develop technologies for immersive user experience in a fully or partially virtual environment. Despite the great progress in visual and auditory technologies, haptics has seen much slower technological advances. The challenge is because skin has densely packed mechanoreceptors distributed over a very large area with complex topography; devising an apparatus as targeted as an audio speaker or television for the localized sensory input of an ear canal or iris is more difficult. Furthermore, the soft and sensitive nature of the skin makes it difficult to apply solid state electronic solutions that can address large areas without causing discomfort. The maturing field of soft robotics offers potential solutions toward this challenge. In this article, the definition and history of virtual (VR) and augmented reality (AR) is first reviewed. Then an overview of haptic output and input technologies is presented, opportunities for soft robotics are identified, and mechanisms of intrinsically soft actuators and sensors are introduced. Finally, soft haptic output and input devices are reviewed with categorization by device forms, and examples of soft haptic devices in VR/AR environments are presented.
