Diamond anvil cell having an integrated sensor

A pressure device comprising:

• a pressure chamber having a chamber wall, said chamber wall comprising a sensor integrated within said chamber wall;
• an electromagnetic radiation source arranged to provide electromagnetic radiation to the defects:
• a detector arranged to detect electromagnetic radiation from the defects;
• and
• a processor controller arranged to control the electromagnetic radiation source to provide electromagnetic radiation to the defects, and to receive a signal from the detector based on electromagnetic radiation detected from defects,
• wherein said sensor integrated in said chamber wall comprises defects.

A pressure device comprising:

• a pressure chamber having a chamber wall, said chamber wall comprising a sensor integrated within said chamber wall,
• wherein said sensor integrated in said chamber wall comprises defects,
• wherein the chamber wall includes a first portion comprising the defects, and a second portion comprising a gasket material contacting the first portion, and
• wherein the first portion is part of a diamond material, and further comprising a conducting material, and an insulating material disposed between the gasket material and the conducting material.
