STMicroelectronics has revealed its contributions to an intelligent toothbrush system from Oral-B. ST’s motion-sensing and control chip inside the toothbrush help develop healthier brushing habits.
Brushing incorrectly can negatively affect oral health. To help people brush like their dental professional recommends and avoid these common oral-health issues, the Oral-B GENIUS intelligent toothbrush system combines position detection technology with triple pressure control and a professional timer.
ST’s low-power three-axis accelerometer permanently captures the orientation of the toothbrush handle while the user is brushing. ST’s 8-bit STM8 microcontroller performs pre-processing of the accelerometer data and other housekeeping functions on the GENIUS toothbrush and leverages ST’s packaging technologies for miniaturisation.
“Our contribution to improving personal healthcare through an electronic toothbrush that brushes like your dental professional recommends is yet another example of how semiconductor technologies help people get more from life,” said Kevin Gagnon, Vice President of Central Sales, Americas Region, STMicroelectronics.
