Photoluminescence (PL) is light emission from a substance after the absorption of photons stimulated by temperature, electricity, pressure, or chemistry doping.
A material with the ability to mimic the human skin in terms of sensitivity, stretchability, and strength could help collect biological information in real time.
Researchers have developed an ultrathin pressure sensor that can be attached directly to the skin. It can measure how fingers interact with objects to produce useful data for medical and technological applications.
Real-time health monitoring and sensing abilities of robots require soft electronics, but a challenge of using such materials lie in their reliability. Unlike rigid devices, being elastic and pliable makes their performance less repeatable. The variation in reliability is known as hysteresis.
At Saarland University, computer scientists have demonstrated how special textiles can be created through a relatively easy method, thus paving the way for new use cases.
Elastic can stretch too far and that could be problematic in wearable sensors. A team of researchers at Yokohama National University has proposed a fix to prevent too much stretching while improving the sensing ability of electronics.
NewTek Sensor Solutions offers its LVDT Position Sensors in a range of construction materials to provide highly accurate and reliable position measurement for applications with extreme conditions.
The new method, based on measuring total pressure of all dissolved gases in the power transformer insulation oil, will help customers detect and repair any air leaks early. This can extend the lifetime of a transformer and lead to significant cost savings.
AW-Lake introduces a new series of Clamp-On Ultrasonic Flow Meters that fasten on the outside of vertical or horizontal pipes ranging in size from ½” through 48”. Housed in a water- and dust-tight NEMA 4X polycarbonate enclosure, the Clamp-On Ultrasonic Flow Meters are compatible with a range of metal and plastic pipe materials and “difficult liquids” such as chemicals, viscous liquids, and abrasives that would damage standard flow meters.
In recent years the development of flood warning systems has benefited from advances in sensor, datalogger and communications technology.
