There are three phases in designing a prototype for measuring the pulse and SpO2. The first is constructing and profiling the optical and electrical characteristics of thin-film BST. From the optical characteristic profiling, it was discovered that there are three wave peaks that are absorbed the most by the film: 450, 600–640, and 900 nm. From the electrical characteristic profiling, it was discovered that the film produced is classified as a photodiode with two sensitivities: exp(–0.0018)/lux when illuminated by white light and exp(–0.0429)/lux when illuminated by infrared light. The second is designing the electronic circuit which consists of an amplifier circuit, filter, and a minimum Atmega328P-PU microcontroller system. From the tests that had been conducted, each circuit succeeded in processing the signal as expected. The third, testing the SpO2 on 20 patients using the prototype and a standard model Elitech Fox-1 oximeter as the reference tool. The results that were recorded demonstrated that the accuracy of the prototype in measuring the SpO2 reached 98% in comparison to the reference tool.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Amplifier circuits,Electrical characteristic,Infrared light,Microcontroller systems,Microcontroller-based,Optical characteristics,Oxygen saturation,Processing the signals[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Barium strontium titanate,microcontroller,optical properties,oxygen saturation,photodiode[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We gratefully acknowledge the funding from the Kementerian Riset, Teknologi dan Pendidikan Tinggi, Republic of Indonesia grant 2019, and we also gratefully acknowledge the funding from United States Agency for International Development through Sustainable Higher Education Research Alliances program Center for Development of Sustainable Region (CDSR) 2018.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1080/00150193.2019.1684755[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
