With the development of the information era, sensors capable of transmitting and detecting information have become the leading way to obtain information. Therefore, building a sensor system with a ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

Researchers have developed a 3D micro-printed sensor for highly sensitive on-chip biosensing. The sensor, which is based on a polymer whispering-gallery-mode microlaser, opens new opportunities for ...

A Norwegian specialist in ultrasonic 3D sensing has developed what it claims is the world's first safety-certified 3D ...

Fig. 1 The simulation of stress distribution in QEPAS: (a) standard QTF, (b) four-prong QTF. In 2002, Tittel et al. proposed a gas sensing technology named quartz-enhanced photoacoustic spectroscopy ...

Sonair says ADAR One was assessed as a human detection sensor according to the IEC 61496 standard for electrosensitive ...

Xarion’s laser-excited acoustics (LEA) is a couplant-free nondestructive testing (NDT) method that uses laser principles and an optical microphone without a membrane. In a single-sided “pitch-catch” ...

Despite their prevalent use in patient treatment, to many, using lasers as surgical tools can seem like something out of science fiction. However, laser-assisted surgery is now a reality and marks a ...
