Self-Power UVC-LED Bacteria Reduction Base on Piezoelectric Nano Generator Service Unavailable

Environmental pollution as an early common reason for natural resources' unsafety, directly menaces human life hygienic indexes. Microbial pollution in water resources, food materials, and common surfaces has produced new problems with infected contacts in daily life activities. Purgation costs and traditional cleaning methods are inadequate and the pollution rate is ascending. Therefore interdisciplinary methods are required to rectify environmental pollution problems smartly while costs and side effects are defined in a sustainability context. The study was conducted to evaluate pulsed mood irradiation operation with UVC LED and a self-power system based on a Piezoelectric Nano Generator (PENG). The study tries to demonstrate the new approach compatibility in an interdisciplinary experiment designed for cleaning environmental pollution. Self-power system in the study is based on produced and tested PENG system that was designed with a proper circuit for a UVC LED power supply. Also, pulsed simulation with a pneumatic cylinder is used to create the required kinetic. Four UVC LEDs were used to make irradiation on diluted samples in the pour plate method. The ritual is an experiment designed in the Design of experiments (DOE) process for an optimized number of tests. The statistical analysis exerted to show impressive elements correlation with disinfection rate. Furthermore, continued irradiation mood was designed for results validation. The exposed samples were analyzed with image processing in python within the OpenCV library to avoid vision errors with edge detection technique. The results showed pulsed base UVC LED with a self-power system reaches high efficiency of disinfection while energy consumption and costs decreased. Most of the experiment cases successfully achieved full disinfection (LOG=۶) and in some cases meaningful (LOG<۶) disinfection was achieved. The study verified the linear and direct relation of irradiation distance, time, and frequency which cause high-efficiency operation of self-power pulsed irradiation system.Environmental pollution as an early common reason for natural resources' unsafety, directly menaces human life hygienic indexes.
