How to check human body vital signs? what kind of sensors?

jmbertoncelli

Hi All,

I would like to check some human body vital signs but I do not have any ideas on what sensors could be used.

Does anyone knows what kind of sensors I could use?

many thanks.

jmbertoncelli,

·· This idea may be a little far fetched, but it may also generate some interest in this new technology. Take a look at the two attachments.

A few ideas:
·1. Heart rate - Sensor can be microphone or skin electrodes (like EKG), or·pulse oximeter
·2. Oxygen level in blood - Pulse oximeter

#2 is very challenging.· Both require some analog electronics to make the signals appropriate for the stamp.

Hope I interpreted your question correctly.·

Thanks a lot!· I shall check if that device is available and what about the cost.

thx.

1) Body temperature ... you can use pretty much any temperature sensor that includes the body temperature range, but accuracy is important ... you want 1/10 degree accuracy.
2) Respiratory rate you can derive from the pulse oximeter data which measures transmission of red light through a finger. As the heart contracts, the blood volume in the fingertip increases and less light gets through. When you inhale, the blood volume in the fingertip doesn't increase as much.
