Claim 0:
1. A wound dressing comprising:
a substantially flexible substrate covered by a conformal coating; and
one or more sensors supported by the substantially flexible substrate and configured to measure characteristics of a wound, the one or more sensors comprising:
an optical sensor configured to detect light components of at least two colors, the optical sensor covered by a substantially non-stretchable coating; and
a white light emitting diode (LED) being separated from the optical sensor by no more than approximately 10 millimeters and covered by the substantially non-stretchable coating,
wherein utilizing the white LED reduces a number of conductive traces as compared to utilizing a color light emitter,
wherein utilizing the white LED reduces dimensions and potential for causing pressure on the wound as compared to utilizing the color light emitter, and
wherein covering the optical sensor and the white LED with the substantially non-stretchable coating prevents formation of localized stress on the optical sensor and the white LED.
