Ultrasonic sensor eliminates inspection blind spots in extreme environments

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching sensors to the inspection target. By enabling remote ultrasonic excitation and reception, the technology is expected to help prevent industrial accidents and eliminate inspection blind spots in high-risk industrial facilities where direct sensor installation has been challenging due to heat, toxic gases, or other hazardous environmental conditions.
