A capsule configured for collecting samples in the intestine, comprising a body delimiting at least one compartment for receiving samples and comprising at least one opening for samples intake, and a mobile mechanism for opening and/or closing the opening controlled by the dissolution of a material which is dissolvable in the intestine.

Device for taking an intestinal sample

Thermo-electric generator which is intended to be immersed in a fluid which contains at least one chemical species, comprising two electrodes each having a first end and a second end, the first ends being connected to each other, the generator being configured to generate an electrical voltage between the two ends when a temperature difference is imposed between each first end and the corresponding second end, the temperature difference being such that one end, referred to as the 'hot end', of each electrode has a temperature which is strictly greater than the temperature of the other end. The hot end of at least one electrode comprises a micro-organism or an enzyme which is capable of causing at least one exothermic reaction involving the chemical species.

Thermo-electric generator, associated implantable device and method

The use of a vapor source () in an isothermal system () to control the crystallization or recrystallization of a sample of solid material () which is initially at least partially amorphous and/or at least partially crystalline and contained within the system (), the vapor source () including at least one solvent for crystallizing the solid material, the vapor diffusion () of which leads to the crystallization or recrystallization of the sample (), the vapor source () being such that the quantities of heat exchanged within the system during the crystallization or recrystallization of the sample () other than the heat of crystallization or recrystallization of the sample are less than approximately 10%, particularly 5%, and advantageously 1% of the heat of crystallization or recrystallization of the sample. The vapor source () is preferably a pure solvent or a solvent mixture in which no solute is dissolved.
