It is challenging to engineer programmable tactile displays to match human haptic abilities. Such displays are often composed of elements whose stiffness contrasts greatly with the softness of many natural materials. Emerging soft material technologies hold promise for their ability to conform to many objects, including the human body. However, rendering localized feedback from soft haptic devices remains challenging. Here, we present the Elastowave, a soft tactile interface that provides localized tactile feedback via a soft, compliant surface. We achieve this by focusing elastic wave fields generated by a compact array of remotely-positioned actuators. Our method is based on new variations of time-reversal focusing techniques for elastodynamic waves. Our system can provide dynamic, single- or multi-point localized tactile feedback with centimeter-scale resolution across a deformable interface with an area of 175 cm 2 . The sizeable displacements of the focused tactile signals enable them to be easily felt, as our experiments show. This work could enable the design of a multitude of new soft tactile interfaces in areas such as creative computing, product design, and augmented reality.
Purpose: Functional electrical stimulation (FES) is a method of activating paralyzed muscles. During FES application, fast muscle fatigue can occur (the inability of stimulated muscles to generate force). Therefore, i...

We theoretically investigate a Thouless pumping scheme in the one-dimensional topological Su-Schrieffer-Heeger (SSH) model for single and multiple band-gap systems when implemented in a discrete nematic liquid crystal arrangement. For an electrically controlled SSH waveguide array, we numerically demonstrate edge-to-edge light transport at low power levels. On the other hand, at higher powers, the transport is frustrated by light-induced nonlinear defect states, giving rise to robust all-optical switching.
Rejecting cosmic rays (CRs) is essential for the scientific interpretation of CCD-captured data, but detecting CRs in single-exposure images has remained challenging. Conventional CR detectors require experimental par...
