Improving low-loss dielectric measurement technique

Scientists from NPL have developed improvements to a technique for measuring dielectric permittivity and loss of materials at MHz frequencies. The method used is named after two NPL scientists who developed in the 1930, Hartshorn and Ward. The findings are presented in the team's paper, "Low loss dielectric measurements in the frequency range 1—70MHz by using a Vector Network Analyser," recently published in Measurement Science and Technology. This method allows the permittivity and loss of a sheet of dielectric material placed between the plates of a capacitor to be determined by resonating it with a coil inductor. The value of the technique is that very low losses can be determined from measurement of small changes in Q-factor.

Repairs using light signals

Repairing complex electrical appliances is time consuming and rarely cost-effective. The working group led by Prof. Dr. Karl Mandel, Professorship of Inorganic Chemistry at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), has now developed a smart microparticle that enables defective components in these appliances to be identified more quickly and easily by using light signals. In the long-term, this could make repairs easier and extend the operating life of devices. The results have been published in the journal Advanced Functional Materials.

Snake skin inspires development of wearable sensors with wide-ranging strain sensitivity

Many bodily functions in humans are manifested by mechanical deformations to the skin—from the stretching, bending and movement of muscles and joints to the flutter of a pulse at the wrist. These mechanical changes can be detected and monitored by measuring different levels of strain at various points throughout the body.

Digital assistants created for e-commerce adapt themselves to each shop's needs

The pandemic has taught us that almost all companies have to sell on the internet. Bots are a technology that facilitates e-commerce. They are digital assistants that can answer customer queries about products that are sold or help to locate them, as well as supporting customers in the purchasing process. "In whatever language; and moreover, chatbots never get tired: They're available 24 hours a day, 365 days a year," said Jordi Cabot, the Universitat Oberta de Catalunya (UOC) researcher who created Xatkit, a company specialized in their development. This technology has existed for some time in big companies and is now also helping improve the digital competitiveness of SMEs. Indeed, the introduction of bots is expanding: this type of artificial intelligence already generates over 40% of the traffic on the internet.
