Bringing a new revolutionary design to switching devices and equipment. Introducing a user-friendly development environment to support manufacturing processes.
The 2nd generation capacitive touch solution to lower hurdles in capacitive touch sensor development.
People now interact with machines through human-machine interfaces (HMI). In this field, as the adoption of capacitive touch interfaces expands rapidly, the use of conventional mechanical keys with limited functions are effectively being replaced. Panels with user-friendly designs can be operated using actions such as finger touches and swipe motions. Capacitative touch technology allows even devices designed for complex and highly skilled operations to be controlled with intuitive finger movements.
As the capacitive touch operation scene expands, panel sensitivity and high-noise resistance have become key requirements in achieving accurate switching movements and sophisticated operational performance. There is also a demand for features involving environmental tolerance to water, dirt, or temperature variations. In addition to these requirements, development periods and costs are also hurdles that need to be considered and overcome.
We, Renesas Electronics Corp., are ready to offer revolutionary solutions to achieve breakthroughs in this field. Click on the video below to experience our advanced technologies and be amazed by the high-level functions and high performance of our capacitive touch panels.
