The present invention relates to an optical biosensor comprising a porous matrix. In the specific case, reference is made to anodized porous alumina, on the surface of which the biological component specific for the analyte in question is immobilized, and to an optical-signal detector connected to said matrix. The present patent further relates to a biosensor having the porous matrix and the optical detector integrated in a single structure, in particular to biosensors with porous matrix other than porous alumina, for example porous silicon.
摘要:
An electrical energy generator device comprising an array of micro-fans each associated to a respective dynamo-electric generator by means of a respective connecting shaft, further comprises, for at least some of the micro-fans (3), a lug element (6) associated to the respective connecting shaft (4) which mechanically co-operates at each revolution with a piezoelectric element (7), for the production of additional electrical energy. In addition or instead of the aforesaid arrangement, it is possible to provide plates (10) made of piezoelectric material which vibrate in the flow of air that invests them, thereby producing electrical energy.
