Sensor-based systems and methods of analyzing shaving usage. A shaving device comprises a blade. The shaving device is communicatively coupled to a sensor and one or more processor(s). Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define one or more shaving strokes based on pressure applied to the user's skin. Based on the one or more shaving strokes, a shaving event can be detected and a shave event count value can be an incremented. The shave event count can be determined to meet or exceed a predetermined threshold value. An output associated with the shaving device may be generated based on the determining that the shave event count value meets or exceeds the predetermined threshold value, the output comprising an indication that the shave event count value meets or exceeds the predetermined threshold value.

A shaving assembly with a housing. A first cutting array is mounted to the housing. The first cutting array has a plurality of non-linear cutting edges. A second cutting array is mounted to the housing. The second cutting array has a plurality of non-linear cutting edges. A first lubricating member is positioned around the first cutting array. A second lubricating member is positioned around the second cutting array.

A system and method for operating a personal grooming/household appliance, including: providing a personal grooming appliance including at least one motion sensor taken from a group consisting of: an orientation sensor, an acceleration sensor, and an inertial sensor; providing a camera associated with the personal grooming appliance; classifying data received from the motion sensor and from the camera using at least one trained machine learning classifier to generate an augmented classification; and providing user feedback information based upon the augmented classification, wherein the augmented classification pertains to a combination of a first state pertaining to a position of the grooming appliance with respect to a user's body part and also pertains to a second state that is different than the first state.

An intelligent shaving system is disclosed herein including a system having a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.

A shaving and grooming apparatus includes a handle and a cartridge attached to the handle. A plurality of upper blades are positioned in the cartridge, where at least some of the plurality of upper blades include curved tips with a curvature that sufficient to prevent the curved tips from contact a cutting surface during use. A plurality of lower blades is positioned adjacent to the plurality of upper blades in the cartridge, where at least some of the plurality of lower blades comprises curved tips with a curvature that sufficient to prevent the curved tips from contact a cutting surface during cutting. At least one of the plurality of upper and the plurality of lower blades has a thickness and flexibility that results in deflection during cutting that increases effectiveness of cutting action. A drive motor moves the plurality of upper blades relative to the plurality of lower blades.

Systems, devices, and methods for applying machine learning to provide feedback related to a personal care device are described. Embodiments of the systems, devices, and methods may identify data from a device such as a razor comprising a plurality of sensors on a razor, predict one or more features such as shaving features based on the data using a machine learning model trained using data from the plurality of sensors, and provide shaving feedback based on the one or more features such as shaving features. Embodiments of the systems, devices, and methods may train a machine learning model, execute a trained machine learning model, capture and/or process data for the machine learning model, provide feedback based on the output of the trained machine learning model, or combinations thereof.
