The world’s fastest hydrogen sensor, is being claimed by Chalmers University in Sweden, which can detect 0.1% hydrogen in air in less than a second. It consists of millions of palladium-gold alloy nano-particles – a material which is known for its sponge-like ability to absorb large amounts of hydrogen. The plasmon phenomenon then causes the sensor ...

Passive RFID tags attached to inanimate objects in the home can have reveal much about the activities of occupying humans, according to the University of Michigan. The system, dubbed IDAct, uses ‘long-range’ (a few metres) 900MHz passive UHF tags and a single antenna in the ceiling of each room. Tags were attached to household items ...

LED maker Osram Opto has joined a German project to explore the principles of high-resolution displays using arrays of micro LEDs (μLEDs). Osram will work alongside ASM Amicra and Fraunhofer IISB in the SmartVIZ project, which has funding from the Bavarian state ministry for regional development. Their potentially high luminance (light output per unit area) could put μLEDs ...

CUI has introduced a series of 3.5mm waterproof audio jack connectors rated to IP67. They come in surface mount, mid mount SMT, and through hole styles, with right-angle orientation and four conductors (sleeve, ring 1, ring 2, tip). There are various sorts, with profiles as low as 5.3mm, typically with elastomer rings that seal against ...

Soft robots can be be designed to move in predictable ways, and then 3D printed, according to Purdue University, which has created customisable soft robot structure, and an algorithm to do the customisation. The specific form of moving structure is a 3D elastomeric lattice, deformed by tension in tendons running through it – pulled by ...

Researchers at MIT are proposing plug-in hybrid vehicles for long-distance heavy transport. The truck would be primarily powered by batteries, but a non-diesel spark-ignition engine would extend range to that of today’s vehicles, according to MIT, avoiding the 10 to 15 tonnes of batteries required in an all-electric truck. The engine would be ‘flex-fuel’, able ...
