The disclosure relates to a flexible active species generator comprising: a first electrode of a conductive metal thin film; a second electrode of a ground electrode; a flexible dielectric layer of an insulator formed between the first electrode and the second electrode; and a plasma resistant functional layer formed between the dielectric layer and the second electrode, wherein the first electrode and the second electrode are electrically connected to an external power supply to generate an atmospheric pressure plasma to generate active species. The flexible active species generator has a plasma resistant function to prevent deformation and decomposition of an insulator caused by the plasma as well as an active species generating function from atmospheric pressure plasma, and has durability and safety, which is thus applicable to articles, foods, garments and human body in various forms.

Dehydration and drying are some of the oldest methods of preserving food and other biological materials such as proteins and both live and dead live microorganisms or their metabolites. The invention disclosed herein seeks a method of further improving the process of preserving biological material by combining the freezing or freeze-drying process with a partial infrared dehydration step. By using infrared radiation energy to perform simultaneous blanching and dehydration, the drying speed is greatly increased and better cellular and molecular integrity is maintained. The invention herein is also particularly useful in connection with cannabis and hemp.

There is disclosed a system and methods for debriding soft tissue from bone using a high-pressure water debridement system. One embodiment includes a cylindrical sleeve bounded by endcaps and having a drainage port positioned for effluent drainage. A central shaft is configured to receive a bone segment and is disposed along a longitudinal center of the sleeve and rotatively coupled between the endcaps. At least one high-pressure water nozzle is disposed on each side of the sleeve, each of which is positioned to impact the bone segment with a high-pressure water stream. A rotational actuator is configured to rotate the central shaft and the bone segment relative to the sleeve and the water nozzles such that when the high-pressure water nozzles are operational, the high-pressure water streams debride the bone segment. Other embodiments are also disclosed.

The invention relates to an electrode array for a dielectrically impeded plasma treatment of a surface of a body, comprising at least one flexible flat electrode (1) and one dielectric (2) consisting of a flat flexible first material which protects the electrode (1) from the surface to be treated, with a layer (3) impeding a direct current flow. The dielectric (2) can lie on the surface to be treated, above a structure (4) with projections (7), air spaces (5) being formed between the projections (7) for the creation of the plasma, which have a side open towards the surface to be treated, and a bottom-side closure as a result of the layer (3) impeding the direct current flow. The structure (4) comprises a plurality of spacer elements (6) consisting of a second material that has less flexibility than the first material, and the projections (7) of the structure (4) are partially or completely formed by the spacer elements (6).
