Alternating Current Electroluminescence Device Guided for Lowering the Blood Pressure

Electroluminescent devices are going through new developments these days. We have proposed a wearable blue light emitting electroluminescence device (EL) for reducing the person’s blood pressure. The EL device was fabricated using screen printing procedure. The developed alternating current electroluminescent device (ACEL) consists of the bottom electrode as indium tin oxide (ITO), barium titanate paste as dielectric layer and silver paste as the upper electrode and ZnS: Cu as the phosphor layer, respectively. The fabricated EL device emits blue light. We have also simulated a PCB in proteus which converts DC voltage to AC voltage. The output AC voltage can be used as the power supply for the EL device. Studies demonstrated that exposure to blue light can reduce the systolic blood pressure of a human being by releasing nitric oxide from skin cells into the circulating blood which reduces the arterial stiffness and contributes to better cardiovascular health. The integration of the power supply PCB with the fabricated electroluminescence display which enables blue light exposure to the person wearing EL device, can decrease the person’s systolic blood pressure. It has been observed from the color purity of the fabricated EL device that the emitted light has coordinates of (0.20,0.23) which represents the region of blue light in CIE Plot.
