Abstract: An ingestible device for sampling material at least one time is provided. The ingestible device includes a first chamber that is enlargeable in volume and that includes an inlet, and that can be filled with the material to be sampled, a second chamber that is diminishable in volume and that includes an outlet, and a reversible actuating mechanism. The reversible actuating mechanism is configured such that triggering the reversible actuating mechanism leads to an enlargement of the first chamber to collect the material to be sampled through the inlet and also leads to a diminishment of the second chamber.

Abstract: An ingestible device for sampling material, sensing, and delivering a drug at least one time is provided. The ingestible device includes a cap and an electronics module configured to slide over each other, allowing for an expansion of the ingestible device. Further, the electronics module includes at least one chamber having an inlet and to be filled with a material to be sampled when the inlet of the at least one chamber overlaps with an opening of the cap, and an actuator positioned at one end of the electronics module covered by the cap. In one example embodiment, the actuator is configured for, when activated, sliding of the cap over the electronics module so that the inlet of the at least one chamber overlaps with the opening of the cap to collect the material to be sampled.

Abstract: An ingestible device for sampling material at least one time is provided. The ingestible device comprises a first chamber being enlargeable in space, comprising an inlet, and to be filled with the material to be sampled, a second chamber comprising a solid block and at least one release member pressed against the solid block to restrict the first chamber from enlarging in space, wherein the solid block is malleable when it is heated above a threshold temperature, and an actuating mechanism. In this context, the actuating mechanism is configured for, when triggered, heating the solid block above the threshold temperature so that the at least one release member is pushed into the solid block allowing the first chamber to enlarge and to collect the material to be sampled through the inlet.

Abstract: Example embodiments relate to devices and methods for collecting and cleaning solid substances. An example device is provided for cleaning dirt particles from a solid body. The device includes a driving shaft configured to rotate along a rotational direction. The device also includes a container arrangement that includes a first slotted container. Further, the device includes a second slotted container attached to the first slotted container and to the driving shaft via a fitting arrangement. The fitting arrangement is configured to simultaneously rotate the second slotted container within the first slotted container in a direction opposite to the rotational direction of the driving shaft.

Abstract: An ingestible device (10) for sampling material at least one time is provided. The ingestible device (10) comprises a first chamber (11) being enlargeable in space, comprising an inlet (6), and to be filled with the material to be sampled, a second chamber (12) comprising a toroidal reservoir (2) being diminishable in space, to be filled with liquid to be delivered, and an actuating mechanism. In this context, the actuating mechanism is configured such that triggering the actuating mechanism leads to deflate the toroidal reservoir (2) so that the first chamber (11) enlarges to collect the material to be sampled through the inlet (6) and the second chamber (12) diminishes to release the liquid through at least one outlet of the toroidal reservoir (2).
