Temperature measurement differences of the skin

[jahahn]

I am tasked with finding a low cost wearable portable method for collecting data on human skin temperature over time. It must be able to record changes to within
+/-.3 degrees. Any suggestions on where I might find this technology would be greatly appreciated.

An IR thermometer?

Did you mean +/- 3°C or +/- 0.3 °C?
What does low cost mean?

They use RDTs for this.
How many points do you need to measure?
You can buy commercial 'select' sensors with good accuracy.
There are very small data loggers (Hobo) that can record data.

Thank you for the information on measuring skin temperature. I will restate the temperature requirement since some people questioned my requirement: +/- .3 degrees C, maximum deviation. This is for human skin temperature. Low cost is something we could purchase for a clinical trial which means the sensors must be well under $200.00/person plus the cost of the device for collecting the data.
