Abstract
A device and method for applying a material to a surface. The device has a sensor and one or more applicator nozzles. The device further includes a reservoir for containing a material to be deposited, and a CPU. The method includes providing information from the sensor about the surface to the CPU, which uses the information to identify where the material is to be deposited and/or how much to deposit.
Claims20
An apparatus for applying a composition to a surface, the apparatus including:
- a. an applicator head comprising a microfluidic die having one or more applicator nozzles;
- b. a reservoir to hold the composition;
- c. a sensor;
- and
- d. a CPU;
- wherein the sensor is configured to sense at least a portion of the surface and provide the CPU with information about the surface, and wherein the CPU analyzes the information from the sensor to identify surface deviations, and the CPU activates the one or more applicator nozzles based on the surface deviations.
A method of depositing a composition on a surface, the method comprising the steps of:
- identifying the surface onto which the composition will be deposited;
- providing a device having a sensor, a reservoir for the composition, a CPU, and at least one microfluidic die comprising at least one nozzle;
- locating the sensor over at least a portion of the surface;
- activating the sensor to acquire information about the surface;
- providing the acquired information to the CPU;
- instructing the CPU to calculate the location of one or more deviatins on the surface;
- and
- activating the at least one nozzle to deposit the composition on the surface.
The use of a device including a sensor, a CPU, a reservoir and a microfluidic die to apply a composition to a surface.
