Position sensing is all about seeing black

Light-based proximity sensors for use in robots and 3D printers must not be fooled by transparent or black surfaces, says Gabriele Fulco A surprising number of systems depend on the ability to accurately locate and identify physical objects. Robots need not only to detect obstacles, but also to identify…

Thin sensor opens way for biometrics in phones

A Norwegian company believes it could have the answer for finger-print sensing in smartphones with a sensor design which is significantly thinner than existing designs. Oslo-based Next Biometrics says the fingerprint sensor could have an impact on smartphone designs because it does not require a metal bezel to…

Panasonic motion sensors pick their target

Panasonic’s AMA and AMB series motion sensors for human motion detectors have trigonometric background suppression, which means they are unaffected by changing scenes or by people passing by outside the detection range. Likely applications include the detection of the presence of an individual in front of machines, at automatic…
