Latest Patents

Lenouvel's latest patents include a "Method and device for changing the pH of a solution." This invention relates to a device designed to modify the pH of a solvent containing a dissolved substance. The device features a housing that interacts with the solvent through a wall that allows the solvent and substance to pass while containing enzymes that convert the substance to generate hydrogen or hydroxide ions. The housing wall is specifically designed to prevent the enzymes from escaping.

Another significant patent is for a "Chemical activation of an actuator or an osmotic motor." This actuator consists of an enclosure with a wall that is impermeable to a first solute but permeable to a solvent. It contains a catalyst that promotes the transformation of a second solute into the first solute, thereby varying the osmotic pressure within the enclosure. The actuator is connected to a deformable chamber that can increase in volume as the solvent moves through osmosis.
