Individual active electronic control system
HYDRO_BOT is the first active moisture transporting membrane and textile laminate that transfer moisture and vapor (passive stage) from one side to another by means of on electroosmosis. It has been tested and developed in sophisticated laboratories (picture above) through collaboration with the Swiss Federal Laboratories for Material Science and Technology (EMPA).
The HYDRO_BOT fabric transports moisture electronically when/if needed independent of any external factors such as temperature and humidity gradients, with direct electronic control of direction and magnitude of transport.
The membrane has a high density of micro pores with charged walls, resulting in a charged layer of liquid with thickness several nanometers. A small applied voltage (ca 1 V) induces the membrane pores to actively pump sweat or condensate from the inside microclimate to the outside. See the demo here.
The HYDRO_BOT membrane has two main advantages compared to conventional ones:
1) A much higher amount of moisture can be transported, by far exceeding even the highest human sweat rates, and
2) the EO membrane functions and keeps the wearer dry independent on weather conditions.
As soon as the activity stops the temperature decreases in relation to RH (relative humidity) levels. The faster the RH decreases, the faster the temperature will go back to a comfortable level. The application of voltage can be seen to reduce drying time of HYDRO_BOT fabrics to a fraction of what other membranes offer.
The principles of Electroosmotic flow was first discovered in 1809 in the Imperial Naturalists of Moscow. It is the motion of liquid through a porous material induced by electronic signals. HYDRO_BOT is a results of more than ten years dedicated research on how to best apply the principles of electroosmotic flow with the right membrane and electronic control system, so that moisture can be effectively transported through microscopic sized pores in the membrane.
