    摘要: A fluid sensor includes a support structure having a top main surface region; a thermal emitter on the top main surface region of the support structure; a thermal radiation detector on the top main surface region of the support structure; and a waveguide structure having a first and a second waveguide section on the top main surface region of the support structure. The first waveguide section guides a first portion of the thermal radiation to the thermal radiation detector and the second waveguide section guides a second portion of the thermal radiation to the thermal radiation detector. The waveguide structure enables an interaction of an evanescence field of the guided first and/or second portion of the thermal radiation with a surrounding fluid.

    摘要: According to an embodiment, an optical MEMS transducer includes a diffraction structure including alternating first reflective elements and openings arranged in a first plane, a reflection structure including second reflective elements and configured to deflect with respect to the diffraction structure, and an optical element configured to direct a first optical signal at the diffraction structure and the reflection structure and to receive a second optical signal from the diffraction structure and the reflection structure. The second reflective elements are arranged in the first plane when the reflection structure is at rest. Other embodiments include corresponding systems and apparatus, each configured to perform various embodiment methods.
