The company's MC 33974 electric field image sensing IC imaging sensor reportedly generates and detects a low-level electric field and powers and supports a microcontroller unit (MCU) in a single chip. It is designed to replace numerous discrete devices previously needed to achieve the same functionality. Target applications include appliances, machine tools, and any other product or system that uses touch panel inputs as a user interface. One such example is that of a flat ceramic cooktop that senses when liquids boil over, and, in response, reduces or turns off the heat automatically.
