Sensors

The sensors used in CARDIOLAB are derived from already medical devices existing on the market, "Commercial of the Shelves" (COTS) philosophy. The definition list of these sensors has been conducted avoiding overlapping with others HRF or ISS resources except when they provide a better operational flexibility. Most of these sensors or their previous models have been flown onboard MIR and/or the Shuttle.

Benefit of experience gained during these operations are obviously taken into account. So, for some of them, we have increased the scientific performances and we have implemented the modifications for a safe use in the ISS environment.

Whenever possible, we try to conduct these development or adaptation with a spin off will. We give in the forthcoming lines a short functional description of them.
