“…Domí nguez et al created a wind sensor for use in Martian atmosphere on a space probe. Pyrex structures were used to maximize thermal isolation to increase sensor sensitivity since Martian pressure is very low (6 mbar) which impedes heat convection compared to normal atmosphere [59]. 3-dimensional MEMS structures have been used for wind sensing [60].…”

Microfabrication has greatly matured and proliferated in use amongst many disciplines. There has been great interest in micromachined flow sensors due to the benefits of miniaturization: low cost, small device footprint, low power consumption, greater sensitivity, integration with on-chip circuitry, etc. This paper reviews the theory of thermal flow sensing and the different configurations and operation modes available. Material properties relevant to micromachined thermal flow sensing and selection criteria are also presented. Finally, recent applications of micromachined thermal flow sensors are presented. Detailed tables of the reviewed devices are included.

“…The REMS sensor suite is an instrument from the Mars Science Laboratory (MSL) on board the Curiosity rover that landed in Mars in 2012. REMS included humidity, pressure, temperature, radiation and wind velocity sensors [2,3,4]. In this paper, we used a 10 prototype of the engineering model developed in 2008 that led to the flight model which is currently on board of the Curiosity rover.…”

The objective of this paper is to obtain time-varying models of the thermal dynamics of a 3D hot thin film anemometer for Mars atmosphere. To this effect, a proof of concept prototype of the REMS (Rover Environmental Monitoring Station) wind sensor on board the Curiosity rover has been used. The self and cross-heating effects of the thermal structures have been characterized from open-loop measurements using Diffusive Representation. These models have been proven to be suitable in the analysis of the thermal dynamics of the sensor under constant temperature operation employing the tools of Sliding Mode Controllers. This analysis allows to understand the long term heat diffusion processes in the whole structure and how they may affect the raw output signals.
