While narrower vertical directivity improves sensor usability, wider horizontal directivity can provide wider coverage with fewer sensors. 'Asymmetric' ultrasonic sensors (Figure 4) are used in such ...

Through use of new materials and structure, the MA200D1 series of high-frequency ultrasonic sensors is said to deliver quicker response times and shorter ringing times, resulting in improved ...

In a study published in the journal Scientific Reports, researchers from Doshisha University developed a unique tunable ultrasonic liquid crystal light diffuser that allows for directional changes ...
