Client Overview
- The client needs smart wearable based on health parameters like blood oxygen and pulse rate
Business Challenge
- The smart wearable design eliminates the requirements to measure blood oxygen level and pulse rate manually.
- Design and developments of the advanced signal processing algorithms for pulse oximeter wearable.
- Blood oxygen saturation is calculated by applying a set of algorithms to differentiate between oxygenated hemoglobin and de-oxyhemoglobin using infrared signals.
Solution Architecture
AumRaj Contribution
- The AFE4403 chip used to obtain a person’s blood oxygen level and pulse rate using an LED skin reflection signal.
- Used mixed-signal processor STM32 to calculate the blood oxygen level and pulse rate using LED reflection signal with motion detection sensor.
- The microprocessor MSP430 to control the whole system.
- Used wireless module to offer wireless communication with IoT cloud.
- Developed mobile app to appear real-time data of oxygen level and pulse rate.
Benefits Delivered
- Easy to monitor blood oxygen level and pulse rate.
- Emergency notification in critical health parameters reading.
- Real-time data on the mobile app, anytime.
