Dyson CameraJet Toothbrush Features In-Mouth Camera

Dyson launched its CameraJet electric toothbrush, marking the brand's first oral-care device to incorporate an embedded macro-lens camera for identifying interdental gaps during brushing. This technology, which Dyson terms Gap Optical Targeting, aims to clean between teeth concurrently with brushing, rather than relying solely on a separate flossing step. The camera, featuring a 100k-pixel resolution, captures 28 images per second. These images are processed by an onboard AI machine-learning algorithm to pinpoint the spaces between teeth. A dome-shaped target lens broadens the camera's field of view for enhanced detection, and a stroboscopic light provides necessary illumination for accurate in-mouth imaging. Once an interdental gap is detected, the CameraJet dispenses precise bursts of liquid. A conical jet delivers up to 0.15ml of liquid between the teeth. This pressurized burst is administered by a diaphragm pump in as little as one-tenth of a second. The device includes an anti-gravity tank designed with an expanding diaphragm to eliminate air pockets, ensuring consistent jet effectiveness regardless of the angle at which the toothbrush is held. Dyson engineered the conical jet shape based on tests with a lab-based proxy plaque, asserting that its sweep is more thorough than a needle-style stream. Complementing the camera system is a high-frequency sonic motor that drives variable oscillations at 245 movements per second. This motor features an anti-stall action to maintain bristle movement for more effective plaque lifting. The toothbrush head is a dual-bristle design, precisely contoured to clean along the gumline. It is also RFID-enabled, allowing it to monitor its own wear and alert users when a replacement is needed. Additionally, a silicone-backed sonic dampener is integrated to provide a softer feel in hand. Users can select from three cleaning modes. The CameraJet pairs with the MyDyson app, providing users with live footage from inside their mouth, coverage mapping to show which areas have been cleaned, and technique feedback to improve brushing habits. The app's coverage mapping utilizes the camera's data to create a visual representation of the user's mouth, highlighting areas that have been adequately cleaned and those that require more attention. This real-time feedback aims to educate users on their brushing efficacy and encourage better oral hygiene practices. The integration of advanced camera technology and targeted liquid delivery represents a significant innovation in the electric toothbrush market, offering a more comprehensive approach to oral care.
