>> This genius Indian guy Parin Dedhi from cornell university made Solar Powered Pulse Oximeter and Heart Rate Meter as final year electronics project.
>> A brief description in his own word “Pulse Oximeter is a non-invasive medical diagnostic device used to detect the oxygen saturation of the blood. Heart rate meter detects the number of beats per minute of the patient, normally referred to as bpm. The pulse oximeter is designed using an infrared and a red LED, projected alternatively on the finger and detection of the transmitted light by a photodiode/phototransistor. The output of the photodiode is given to a transimpedance amplifier, and further amplified and filtered before giving to the Atmega644 microcontroller. The ADC in the microcontroller will convert it into digital form, and later display the value of SpO2 and heart rate on a 16*2 LCD screen. The goal of the project is to develop a low cost pulse oximeter and heart rate meter powered by solar energy. The idea was conceptualized due to the fact that the oxygen saturation of blood is one of the most important parameter to be monitored, and the pulse oximeter being low cost and solar powered, allows it to be accessed by the developing and under developed nations.”
