Breathing walls: The design of porous materials for heat exchange and decentralized ventilation
Published in Energy and Buildings

Researchers at Harvard University studied how pores in building materials can be designed,
such that incoming fresh air can be efficiently tempered while conduction losses are kept to a minimum.
With the use of gSKIN heat flux sensors they could determine the total convective heat transfer
in blowing and sucking mode through porous materials.

Bioinspired microactuators for zero-power heat flux regulation
Published in Institute of Electrical and Electronics Engineers

Researchers from ETH Zurich developed a zero-power, bioinspired heat sink where the thermal resistance is reduced with increasing ambient temperature whereas the heat flux through the heat sink is increased. This effect is established by microactuators with a very high temperature sensitivity. With the usage of gSKIN sensors they could characterize the properties of the developed device.
