Judul : Application of thin film barium strontium titanate (BST) in a microcontroller based tool to measure oxygen saturation in blood
Abstrak :

Tools to measure pulse and blood SpO2 have been made using thin- film barium strontium titanate (BST) as the sensor. There are three phases in designing a prototype for measuring the pulse and SpO2. The first is constructing and profiling the optical and electrical charac- teristics 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 char- acteristic profiling, it was discovered that the film produced is classified as a photodiode with two sensitivities: exp(–0.0018)/lux when illumi- nated by white light and exp(–0.0429)/lux when illuminated by infra- red light. The second is designing the electronic circuit which consists of an amplifier circuit, filter, and a minimum Atmega328P-PU micro- controller system. From the tests that had been conducted, each cir- cuit 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 measur- ing the SpO2 reached 98% in comparison to the reference tool.
