    "patent_abstract": "A method of manufacturing a transducer includes forming a support structure from a transparent material, the support structure configured to support a sensing element and deform in response to an environmental parameter. Forming the support structure includes modifying a first portion of the transparent material by exposing the first portion to laser radiation, and removing the first portion by an etching process. The method also includes disposing the sensing element at a fixed position relative to the support structure, the sensing element configured to generate a signal indicative of deformation of the support structure.",
