Heat-resistant ultrasonic transducers

Technical systems must be regularly checked for defects, such as cracks. Up to now, piezo sensors measuring pressure, force or voltage have been used to reliably detect such faults – but only to around 200 degrees Celsius. ...

Student-built innovations to help improve and save lives

Nanyang Technological University (NTU) students have developed new and practical life-saving innovations inspired from everyday problems, including improving the safety of cyclists on the roads and keeping the dengue menace ...

A low-cost, finger-nail sized radar

European researchers have squeezed radar technology into a low-cost fingernail-sized chip package that promises to lead to a new range of distance and motion sensing applications. The novel device could have important uses ...

'Virtual bumpers' can help avoid crashes

Three new Cadillac models, including the ATS sport sedan, have a new advanced safety system that can automatically stop the vehicle in low-speed conditions to help avoid crashes. 

Flaky graphene makes reliable chemical sensors

Scientists from the University of Illinois at Urbana-Champaign and the company Dioxide Materials have demonstrated that randomly stacked graphene flakes can make an effective chemical sensor.

Tacit hand device steers blind to safety (w/ video)

(PhysOrg.com) -- A hand device called the Tacit can help the blind and visually impaired move around safely in complex environments. Wrist-mounted, the device uses ultrasonic sensors mounted above the knuckles that can pick ...

High definition diagnostic ultrasonics on the nanoscale

Scientists and Engineers at The University of Nottingham have built the world's smallest ultrasonic transducers capable of generating and detecting ultrasound. These revolutionary transducers which are orders of magnitude ...
