Researchers from MIT and MGH have developed a non-contact based ultrasound device that uses skin-safe lasers to induce ultrasound waves, mounter on a robot arm.
Researchers at MIT have developed a low power, no battery underwater backscatter communication system, which is made from piezoelectric materials that detect and reflect encoded data using background sound waves. The system can theoretically transmit over kilometer long ranges, and could be used to provide data connectivity to offshore monitoring stations or renewable energy systems.
Low Tech magazine published an interesting article about heat generating windmills and how efficient they are using different configurations and technologies. The article demonstrates that a heat generating windmill can cover 40-70% of modern heating needs.
Japanese company Futto have created a rubber net device that aids people learning to walk again. The device aids muscles by acting in place of weakened tendons.
Digital bioacoustics uses recording devices and AI to decode animal languages and helps us understand and sometimes synthesize them! Scientists at Tel Aviv University can translate Egyptian fruit bats, and researchers at Freie Universität Berlin have created a RoboBee that can give instructions to other bees in the hive!
Scientists at North Carolina State University have developed a metal gel that can be used in 3D printers. After printing, the gel hardens when water and hydrochloric acid in the gel evaporates, producing a rigid metal structure.
An interesting article in The Guardian describes two discoveries that show hygroelectricity, which is generating electricity from the charge in humid air.
Bjørn Karmann created an AI prompt camera called Paragraphica, that can generate a photo using in situ to generate an AI representation of the location of the camera with added context such as weather, time of day, date, and points of interest.
Engineers at University of Massachusetts Amherst have developed a method to generate electricity from air using two porous nanofilms that create an imbalance of charge between water droplets. Stacking this air-gen device could allow the technology to scale up to the kilowatt level of electricity generation.
