The present invention provides a drainage net for suppressing biofilm formation, the drainage net including a drainage net main body having a cylindrical structure opened at an upper side thereof and having drainage holes, a first electrode disposed outside or inside the main body, a second electrode grounded, spaced apart from the first electrode at a predetermined interval, and disposed outside or inside the main body, and a voltage supply unit configured to apply, to the first electrode, at least one of an alternating current (AC) voltage, a direct current (DC) voltage, and a voltage in which the AC voltage and the DC voltage are superimposed.

A system and method for controlling microbial growth on and in medical devices and implants, especially biofilm infections, involves using pulsed electric fields (PEF). To eradicate at least a portion of a biofilm on a medical implant, for example, 1500 volts can be applied through an electrode system, with pulse duration of 50 μs and pulse delivery frequency of 2 Hz. In the clinical setting, systemic microbial therapy can be combined with PEF to achieve a synergistic effect leading to improved eradication of infections.

An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

A soil disinfector comprising an insulating endless belt with at least one row of positive electrodes and at least one row of negative electrodes mounted on the endless belt. The electrodes are mounted with their heads on the inside of the belt and their bodies pointing outward from the belt, the electrodes being configured to penetrate the soil. The electrodes take their power from a power source, the power source being connected to the electrodes via sets of rows of rollers and sets of rows of stationary conductive contact plates, at least one set of each being positive and at least one set of each being negative. The soil disinfector also has sensors to detect soil conditions and a processor to alter power applied to the soil based on the soil conditions.

The field of this invention is technology that supports and enhances natural face-to-face communication. Throughout the recent Pandemic, people have been adversely affected by the loss of real face-to-face human contact. The invention provides one or more safe ‘meeting spaces’ through which persons can talk to each other normally, without the risk of airborne pathogens passing between them. The meeting space of the invention offers no physical barrier such as glass, which would reduce the quality of communication and diminish the user experience. Persons may see and hear each other through the meeting space but pathogens cannot substantially pass through it. Various ways are provided that substantially destroy/inactivate/remove pathogens from the meeting space(s). Some embodiments are sustainable, carbon neutral and solar powered. Others are highly energy efficient. Further refinements create a pleasant environment for conversation and enhance the user experience.
