Waterproof ‘e-glove’ could help scuba divers communicate

Nanowerk  April 10, 2024 Existing tactile sensing gloves fall short in terms of user comfort and are ill-suited for underwater applications. Researchers in China proposed and constructed a flexible hand gesture recognition glove (GRG) that contained high-performance micropillar tactile sensors (MPTSs) inspired by the flexible tube foot of a starfish. The sensor has a wide working range, superfast response time, reliable repeatability, and a low limit of detection and they were waterproof. When integrated with machine learning algorithm, the GRG system achieved intelligent recognition of 16 hand gestures under water, extending real-time and effective communication capabilities for divers. According to […]

Researchers invent flexible and highly reliable sensor

Science Daily  November 2, 2020 Real-time health monitoring and sensing abilities of robots require soft electronics. Unlike rigid devices, being elastic and pliable makes their performance less repeatable due to hysteresis. Researchers in Singapore have developed a sensor, Tactile Resistive Annularly Cracked E-Skin (TRACE) which addresses the trade-off between sensitivity and hysteresis in tactile sensors when using soft materials. They discovered that piezoresistive sensors made using an array of three-dimensional metallic annular cracks on polymeric microstructures possess high sensitivities, low hysteresis over a wide pressure range and have fast response. They have demonstrated that TRACE sensors can accurately detect and […]
