A wireless epidermal electrotactile interface is demonstrated through integration of skin-conformal electrodes and flexible circuitry, addressing existing limitations in haptic technology caused by mechanical mismatch and system-level integration challenges. This electrotactile system achieves low stimulation thresholds (<20 V) through optimized electrode-skin modulus matching and improved electrochemical interfaces, enabling pain-free tactile sensation generation across finger pads. The millimeter-scale architecture incorporates multiplexed stimulation channels that spatially map to ISO-standard Braille configurations, demonstrating 91.

The accurate smartphone-based pedestrian navigation significantly depends on the precise heading estimation. However, heading estimation is still a challenging problem in most pedestrian navigation applications because of the bias of low-cost smartphone sensors, thermal drift with long-term operation, and the unexpected changes in the carrying mode of handheld devices. To address these challenges, many existing methods based on pervasive resources encounter severe errors.

High-resolution electronic tactile displays stand to transform haptics for remote machine operation, virtual reality, and digital information access for people who are blind or visually impaired. Yet, increasing the resolution of these displays requires increasing the number of individually addressable actuators while simultaneously reducing their total surface area, power consumption, and weight, challenges most evidently reflected in the dearth of affordable multiline braille displays. Blending principles from soft robotics, microfluidics, and nonlinear mechanics, we introduce a 10-dot-by-10-dot array of 2-millimeter-diameter, combustion-powered, eversible soft actuators that individually rise in 0.

Objective: Laryngeal dystonia (LD) is associated with involuntary laryngeal muscle spasms that impair speech. Research established that vibrotactile stimulation (VTS) of the larynx can lead to short-term improvements in voice quality in LD. To determine its usability and potential effectiveness in nonclinical settings, this study evaluated a 2-month use of in-home VTS as a noninvasive treatment for LD.

Background: Visually impaired individuals face significant challenges in maintaining oral hygiene due to reliance on visual cues. Conventional oral health education (OHE) often fails to address their needs, leading to disparities in oral health outcomes. The aim of this study was to assess and compare the effectiveness of three customized oral health education strategies-Audio only (Group 1), Audio + Braille (Group 2), and Audio + Tactile Model (Group 3)-on oral health Knowledge, Attitude, Practice (KAP), and clinical oral hygiene status among institutionalized visually impaired individuals in Lucknow, India.
