What are optical rotary encoders?
Accurate measurement of rotary shaft motion, including position, velocity, and acceleration, is crucial in numerous applications. This is typically achieved by incorporating a rotary encoder into the motor or shaft assembly. While “rotary encoder” is often abbreviated to “encoder,” it should not be confused with other electromechanical or electronic encoding devices used for data format […]
Flexible artificial intelligence optoelectronic sensors towards health monitoring
Researchers at Tokyo University of Science (TUS) have developed a flexible paper-based sensor composed of nanocellulose and zinc oxide (ZnO) nanoparticles that operate like the human eyes and brain. The sensor is energy-efficient, responds to optical input in real-time, and is both flexible and easy to dispose of, making it ideal for health monitoring applications. […]
What are next generation bio sensing techniques? Part 2
Part 1 of this blog explored research into localized surface plasmon resonance (LSPR) sensors. This part discusses a surface plasmon resonance/surface-enhanced Raman scattering (SPR/SERS) dual-mode plasmonic biosensor and two other sensing techniques. The SPR/SERS biosensor based on catalytic hairpin assembly (CHA)-induced Au nanoparticle (AuNP) network was proposed for highly sensitive and reliable detection of a […]

High optical output laser diode targets LiDAR apps
ROHM Semiconductor announced they have developed a high optical output laser diode, the RLD90QZW3, for applications such as AGVs (Automated Guided Vehicles) and service robots in the industrial equipment sector and robot vacuums in the consumer field that incorporate LiDAR for distance measurement and spatial recognition. In recent years, LiDAR has been increasingly adopted in […]
What is the difference between an absolute and incremental position encoder?
Measuring the position of a rotating shaft, speed or direction of motion typically requires a rotary encoder. The two main types of encoding techniques are: absolute and incremental encoders. The absolute encoding technique provides a specific and unique position value for every point of rotation when it is switched on. Absolute encoding is commonly achieved […]
