| Scope of work: |
“SIDS” or “Sudden Infant Death Syndrome” is a phenomenon that occurs in infants and has been linked to environments with low air flow and/or low levels of oxygen. The end goal of this project is to produce a low cost, low power, portable pulse oximeter that will be affixed to an infant’s leg and used to remotely monitor blood-oxygen levels and trigger an alarm if blood-O2 levels fall below a certain critical threshold. This oximeter will operate off of a single medical type lithium battery (2032) and will use a red/IR LED driver and a photodiode receiver as the light level sensor. Likewise, it will require clever digital and analog signal processing as well as an MSP430xxxx and/or DSP to decrypt the oxygen absorption levels and provide analog signal adjustments and digital timing. After processing this information will be transmitted to a remote laptop or Iphone application which will be the end monitoring source and visible face of this project.
A recommended team will include:
Electrical Eng majors for the Analog LED driver and photo sensor, I-V conversion stage for photodiode current, intermediate filtering, gain, and offsetting stage, ADC timing, RF communication, uC/DSP programming.
A computer engineer for coding Iphone application or Laptop program. Which of these is chosen will be based on Zigbee or Bluetooth.
An optical engineer for optimizing the distance, aperture, and calibration of LED and photodiode |
