Electric toothbrushes are becoming more efficient, intelligent and user friendly offering a better user experience and improve dental care. They protect teeth and gums better through refined motor control resulting in a gentler brushing action, they monitor brushing duration, frequency and brushed surface progress over time thanks to embedded sensors. They provide information on brushing habits and effectiveness to smartphone applications thanks to built-in wireless connectivity. And they offer extended battery life and contactless wireless charging.

ST’s offering provides a broad portfolio of solutions that enable designers to create innovative toothbrushes integrating advanced features. A key product family is our fully integrated STSPIN motor drivers providing very low power consumption and full motor protection. Other key products include high accuracy and low power motion sensors including embedded event detection features, sensor fusion and software tools that allow to build proprietary algorithms, Wireless battery charger compliant with the most recent standard to ensure high efficiency and compatibility with standard chargers, low power microcontrollers, and ultra-low power Bluetooth low energy system-on-chip for seamless communication with smartphones.
