Single IC for 3D electric field imaging

26 February 2003 Electronics Technology Access Control & Identity Management

Motorola is offering what it claims is the industry's first IC for three-dimensional electric field imaging. The single chip MC33794 device generates and detects a low-level electric field and powers and supports a microcontroller unit (MCU). It can replace more than 70 components for creating embedded systems that require non-contact sensing and three-dimensional (3D) electric field (e-field) imaging. The IC integrates support for a microcontroller and up to nine simple electrodes, which can be used independently to provide information on the size or location of an object in a weak electric field. Target applications of the IC include appliances, machine tools, automotive safety systems, and virtually any product or system that uses touch panel inputs as a user interface.
