Science Daily June 29, 2020 An international team of researchers (China, USA – UCLA) has developed wearable sign-to-speech translation system composed of yarn-based stretchable sensor arrays and a wireless printed circuit board. It offers a high sensitivity and fast response time, allowing real-time translation of signs into spoken words to be performed. By analysing 660 acquired sign language hand gesture recognition patterns, they demonstrated a recognition rate of up to 98.63% and a recognition time of less than 1 second…read more.

‘Breathable’ electronics pave the way for more functional wearable tech
Science Daily April 30, 2020 Researchers at the North Carolina State University used the breath figure method to create a stretchable polymer film featuring an even distribution of holes. The film is coated by dipping it in a solution that contains silver nanowires and heat-press the material to seal the nanowires in place. The resulting a few micrometers thick film showed an excellent combination of electric conductivity, optical transmittance and water-vapor permeability and stability in the presence of sweat and after long-term wear. They demonstrated the material’s potential for use in wearable electronics and electrophysiologic sensors…read more. TECHNICAL ARTICLE
A wearable device so thin and soft you won’t even notice it
Science Daily August 2, 2019 A team of researchers in the US (UT Houston, University of Colorado) has developed a multifunctional soft stretchable HMI device based on sol-gel-on-polymer–processed indium zinc oxide (IZO) semiconductor nanomembrane electronics. Stretchable resistive random-access memory (ReRAM) for data storage components as well as field-effect transistors for interfacing and switching circuits, temperature, strain, and ultraviolet sensors are developed. The devices are constructed in an ultrathin (3 to 4 μm) and narrow meandering serpentine-shaped open-mesh configuration, which renders their mechanical stretchability (stable operation up to 30%). It collects signals from the human muscle, directly guides the robot, and […]
