The authors would like to thank Prof. Lex Smits for making all of the above-described sensors possible by pioneering MEMS-based turbulence measurements and for his many helpful comments and suggestions. This work was made possible through ONR grants N00014-12-1-0875 and N00014-12-1-0962 (program manager Ki-Han Kim) and the Fondation pour l’Etude des Eaux du Léman (FEEL). The development of the T-NSTAP and the q-NSTAP is part of the international, interdisciplinary research project elemo ( http://www.elemo.ch ) whose objective is to study and preserve freshwater resources.

N2 - A collection of nanoscale sensing devices developed specifically for high-frequency turbulence measurements is presented. The new sensors are all derived from the nanoscale thermal anemometry probe (NSTAP), which uses a free-standing platinum wire as active sensing element. Each sensor is designed and fabricated to measure a specific quantity and can be customized for special applications. In addition to the original NSTAP (for single-component velocity measurement), the new sensors include the T-NSTAP (for temperature measurement), the x-NSTAP (for two-component velocity measurement), and the q-NSTAP (for humidity measurement). This article provides a summary of the NSTAP family including details of design and fabrication as well as presentation of flow measurements using these sensors. Also, a custom-made constant-temperature anemometer that allows proper operation of the NSTAP sensors will be introduced.
