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. Capacitive 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.
Renesas offers revolutionary design to switching devices and equipment with our 2nd generation capacitive touch solution that enables a user-friendly environment to support manufacturing processes and lowers hurdles in capacitive touch sensor development.

We prepared a demonstration of self-capacitance waterproof button. The solution can compare the Waterproof of GND shields and Active shields for self-capacitance button.
The touchless button reference design applies Renesas capacitive solutions to detect approaching fingers and hands without physical contact. Two types of reference design, Demo solution and electrode boards are available.
The 3D gesture demo applies Renesas' capacitive touch solution to realize an HMI that detects gesture motions (up and down, left and right, and forward and back) of a hand in a three-dimensional space. A standard version (160mm sq.) and small version (80mm sq.) are available.
As a capacitive sensor application, we prepared a demonstration of water level measurement using the Renesas capacitive touch solution.
