Overcome the Top 4 Challenges of Capacitive Sense Design

From light switches to washing machines, developers are adding capacitive sense to hundreds of devices that need a sleek, low-profile interface surface, improved long-term reliability compared to mechanical buttons, and a customized interface. All capacitive sensing solutions essentially perform the same task. Sensors use integrated CMOS designs combined with external capacitive components to measure minute analog changes. Then, post-sample processing interprets these changes to characterize user touches. Although capacitive sensing solutions have been on the market for decades, this technology still has formidable design barriers, especially in early-stage development. Engineers must do the following to create an optimal solution:
