Claim:
1. A heat flux sensor comprising: at least one first support; at least one first membrane being suspended relative to the first support by a set of at least four nanowires providing mechanical suspensions connecting from the at least one first membrane to the first support; said first membrane being made from at least one current-conducting material; the at least four nanowires being made from a current-conducting material; two nanowires of the set of at least four nanowires connected respectively between 1) one of two terminals on the first support and 2) the at least one first membrane, the two terminals capable of providing a current from a current source to polarise the first membrane and said two nanowires acting as a heater for heating said first membrane; and at least two nanowires of the set of at least four nanowires being connected to a device for measuring the voltage at the terminals of the first membrane.
