Abstract: A triboelectric wearable device (100) and a method for physiological monitoring, comprising: a support element (101); a first element (102) consisting of a first metallic contact (102a) and a second metallic contact (102b) between which is placed a dielectric layer, said first element (102) being able to be placed in contact with a wrist (50) of a user and bonded to the support element (101); a second element (103) overlapped and bonded to the first element (102) and to the support element (101). The triboelectric wearable device (100) further comprises an electronic interface (104) for acquiring and processing the signal generated by means of the triboelectric effect in the blood vessels of the user near the wrist (50), said electronic interface (104) being housed into the support element (101) and connected to the first metallic contact (102a) and to the second metallic contact (102b) of the first element (102).

Abstract: A microfluidic device for cell culture and screening, including a covering element with a plurality of openings configured for introducing and collecting fluids, and a central through hole; an intermediate element with a plurality of microchannels, a plurality of supply tanks and at least one waste tank, and a blind bottom cavity; a lower element, with a collecting tank and a recessed central portion; and a slide housed in a housing pocket. The intermediate element is interposed between the covering element and the lower element to form an upper optical window and at least one culture chamber. The plurality of microchannels puts in fluid communication the plurality of supply tanks, the at least one culture chamber and the waste tank.
