Infineon Technologies AG introduced the company's fifth-generation CAPSENSE capacitive and inductive touch-sensing human-machine interface (HMI) technology. The next-generation CAPSENSE solution embedded in PSoC microcontrollers can provide higher performance and lower power consumption for demanding user interfaces in home appliances, industrial, consumer, and IoT products. Enhanced HMI supports advanced solutions, such as proximity sensing with improved detection range, gesture detection and directionality, and hover detection for advanced touch screens in the future.

The new CAPSENSE technology has ten times higher performance and one-tenth of the power consumption than previous generations of products, enabling designers to develop a more intuitive user interface while significantly reducing overall power consumption to meet battery-powered IoT Equipment requirements. The latest generation of CAPSENSE is ideal for home appliances and industrial applications, including smart door locks, smart switches, thermostats, smart speakers, power tools, industrial touch screens, and other IoT devices. This new technology is also very suitable for applications with larger touch screens in industrial and household appliances products (including induction cookers, washing machines and dryers, refrigerators, ovens, etc.).

Infineon’s proprietary CAPSENSE technology enables designers to develop more advanced HMIs on future devices with various touch-sensitive user interface requirements. With ultra-low power consumption and the ability to fit in smaller form factors, this technology is also an ideal choice for touch interfaces on wearable devices, ear-worn devices, and smart IoT applications. The new CAPSENSE technology supports advanced HMI solutions such as proximity sensing with improved detection range, gesture detection and directionality. The new autonomous sensing mode can run without a CPU, thereby reducing power consumption, while the new proportional sensing architecture and differential signal path can improve noise immunity and performance.
