1. A gas measurement device, comprising:
an optical source configured to emit a series of bursts;
a light sensitive medium including a sensing film adapted for adherence to an epidermal surface and responsive to gaseous diffusion from the epidermal surface, the light sensitive medium emits a photoluminescent response, from an oxygen based decay following each burst from the optical source, the emitted light based on a gaseous diffusion through the light sensitive medium;
a receptor disposed for receiving the emitted light, the optical source adjacent to the light sensitive medium and between the receptor and the light sensitive medium; and
a circuit including logic coupled to the receptor for computing a quantity of the gaseous diffusion based on the emitted light.
