Abstract
The present invention relates to a method for making a device provided with at least one closed enclosure filled with at least one liquid and closed with at least one flexible membrane based on an elastic material, comprising the steps of: a) depositing on a support (100) at least one given material in liquid form, b) at least partly solidifying said given material (130), c) depositing at low pressure an elastic material onto said solidified material so as to form a membrane, the membrane and the support forming at least one closed enclosure filled with said given material, d) melting said given material (130), so as to again liquefy said given material in the closed enclosure.
Claims20
A method for making a device provided with at least one closed enclosure filled with at least one liquid and closed with at least one membrane, comprising the steps of:
- a) depositing on a support at least one given material in liquid form,
- b) at least partly solidifying said given material,
- c) making a membrane by low pressure deposition onto said solidified material, the membrane and the support forming at least one closed enclosure filled with said given material, and
- d) melting said given material, so as to again liquefy said given material in the closed enclosure.
A method for making a device provided with several separate closed enclosures filled with at least one liquid and closed with at least one membrane, comprising the steps of:
- a) filling of at least one said enclosure on a support with at least one given material in liquid form,
- b) at least partly solidifying said given material,
- c) making a membrane by low pressure deposition onto said solidified material, the membrane and the support forming several separate closed enclosures filled with said given material, and
- d) melting said given material, so as to again liquefy said given material in the closed enclosure.
A method for making a device provided with several separate closed enclosures filled with different liquids and closed with at least one membrane, comprising the steps of:
- a) filling of at least one said enclosure on a support with one given material and the filling of at least one enclosure with another given material, both materials being in liquid form,
- b) at least partly solidifying of said another given material,
- c) making a membrane by low pressure deposition onto said given materials, the membrane and the support forming several separate closed enclosures filled with said given materials, and
- d) melting said another given material, so as to again liquefy said given material in the closed enclosure.
