ring pulse oximeter

摘要

the ring uses the reflection measuring method and optionally by transmission. it consists of four main parts. the circuit of measurement and data acquisition. it measures the pulse oximetry, temperature as well as the movement of the finger. the processing circuit.it takes the data and the processing needed to extract the improve measures and other parameters such as heart rate, blood pressure, and others. circuit for power supply. the food is in a replaceable battery (can be rechargeable and can collect energy from voluntary or involuntary.the latter circuit is transmitted. it communicates via a wireless network, bluetooth, zigbee, etc.), with the outside world, which may be a mobile phone or a dedicated device or labtop.
