1. A method comprising:
- providing an oximeter device comprising a sensor head comprising a probe face that faces a tissue to be measured and a handle;
on the probe face, forming first, second, and third sensor structures;
positioning the second sensor structure at a first distance from the first sensor structure;
positioning the third sensor structure at a second distance from the first sensor structure, wherein the first distance is different from the second distance; and
providing an elastic member comprising a spring constant coupled between the sensor head and handle.

Abstract
An oximeter probe includes sensor head with a probe face having one or more sensor structures to make measurements, a handle, and an elastic member connected between the handle and the base. A user can hold the handle while measurements are made and the elastic member permits the handle to flex relative to the sensor head with one or more sensor structures.
