Abstract

Hairstyling tool of the comb or hairbrush type, comprising a handle and a body, an electric battery a force sensor, an electronic unit configured to capture and format signals provided by the sensors, a wireless communication means for transmitting data to a remote entity, by means of which information about the movements executed by the tool and the forces it undergoes can be transmitted to the remote entity, the remote entity being able to send information back to the user of the tool about the hair being styled.

First claim

The invention claimed is:

1. A system comprising a hairstyling tool and a remote entity configured to be connected together by a wireless connection, the hairstyling tool being a comb or a hairbrush,
the hairstyling tool comprising:
a handle and a body, provided with teeth and/or bristles,
at least one movement sensor,
at least one three sensor configured to measure a torsional or bending stress exerted between the handle held by a user and the body engaged with the hair of said user,
at least one electric field sensor suitable for measuring an electric field generated by the electrostatic charges resulting from hairstyling movements,
an electronic control unit, configured to capture and format signals provided by the at least one force sensor, and by the at least one movement sensor, and the at least one electric field sensor,
at least one wireless communication coupler suitable for data transmission to the remote entity,
wherein the wireless communication coupler is configured to transmit to the remote entity data corresponding to information on the movements executed by the hairstyling tool through the hair and stresses entailed therefrom, as well as electric field sensed along said executed movements,
wherein the remote entity comprises at least one application configured to analyze the received data to formulate recommendations for hair care or products to be applied to the hair of the user, wherein the remote entity is configured to provide the recommendations to the user of the hairstyling tool via a display screen.

2. The system according to claim 1 , wherein the hairstyling tool further comprises at least one camera and/or optical sensor suitable for capturing images of the hair and/or scalp, the electronic unit being configured to format and transmit these images.

3. The system according to claim 1 , wherein the hairstyling, tool further comprises at least one memory space suitable for storing data collected during the hairstyling movement or movements, prior to subsequent transmission to the remote entity.

4. The system according to claim 1 , wherein the remote entity is formed of a mobile device, configured to display some of the data transmitted by the hairstyling tool and provide information to the user about the hair being styled.

5. The system according to claim 1 , wherein the remote entity comprises both a mobile device and a computer server that can connect to the mobile device in order to exchange summary data concerning the hairstyling.

6. The system according to claim 1 , wherein the hairstyling tool further comprises at least one microphone suitable for measuring the vibrations generated by the hairstyling movement, the electronic unit being configured to format and transmit the corresponding data.
