Application Example
By utilizing glass substrates, which enable larger sensing areas than silicon substrates, we realize large-area, high-resolution, high-speed sensors capable of monitoring conditions across wide areas in real time. In addition, by applying display technologies to high-resolution area sensing, we can visualize conditions that are difficult to detect with point sensors as highly accurate spatial distributions. Our technologies support a variety of sensor applications, including capacitive touch sensors, X-ray sensors, and pressure sensors, and are utilized in fields such as security, medical imaging, and load and contact detection.
