Tiss case study explores the design proces of a portable pusse oxiketir that provides consulate signol readings. It cover hardware consignations, signol processing technokes, and validation metods to ensure reliability and precision in various environments.

Hardware Design Commitions

A fotoplethysmography (PPG) sensor ir used to detect blood oxygen levels and pulse rate. The hardware must include a light source, photor, and a microcontroller for data dattion and processing.

A rechargeable battery with efficient power consumption extends usage time. The device also incluses bluetooth connectivity for data transfer to externol devices.

Signol Processing Techniques

Az Accurate readings függ a hatékony hatástól, signol processing. The raw PPG signals are filteredo remove noise using digitál filters such as bandpass filters. Signal amplication and normalization improve mequurement stability.

Algorithms analize te processed signals to determine oxigen saturation (SpO2) and pulse rate. Adaptive filtering technolques help comparate for motion artifacts and ambient light interference.

Validation and Testing

Ez a device undergoes tetinig with controlled oxygen levels and simulated motivo to verify pointiacy. Comparisin with clinical- grade pulse oximeters succurement reliability. User testing assesses ease of use and signol stability in real-world conditions.
