Abstract: An electrochemical sensor (10) for measuring biochemical parameters in the sap (L) of a plant (P), comprising: —a channel in which the sap (L) of a plant (P) flows; —a first electrically conductive filament (11) which crosses the channel; —a control electrode (12) which crosses the channel; wherein the channel comprises a conductor vessel (C) of a trunk (D) of the plant (P), and wherein the first filament (11) comprises a textile fiber (110) coated with a layer (111) of conductive polymer.

Abstract: Embodiments of the invention disclosed herein are directed to articles of clothing that allow for monitoring of different analytes (e.g., electrolytes and molecules) in human sweat during fitness activity, while training, or simply in everyday life. The clothing includes a sensor system completely integrated in textile such that every sensing part is made of textile fibers. The clothing is able to control, collect, analyze, and expel the sweat over time. The textile sensor allows a spontaneous absorption of body sweat directly from the skin, while it is produced, using the hydrophilic natural properties of the textile. Then, once adsorbed, the flux of sweat is controlled and guided through the textile using a gradient of the textile's hydrophilic properties. The sweat guided through the textile is analyzed through an electrochemical sensor woven into the textile. Finally, the sweat is collected in a reservoir and expelled for evaporation.

Abstract: The present invention relates to a zinc oxide-based piezoelectric device, utilizable both as a sensor and as an actuator. More in particular, the present invention relates to a piezoelectric device (1, 101) comprising at least two carbon fibre crossed yarns (2a, 2b; 102a, 102b), at the intersection of which a zinc oxide layer (3, 103) in nanorod form is arranged, wherein an end (4a, 4b) of each of said yarns (2a, 2b; 102a, 102b) is connected to an operative unit (5).

Abstract: A method for diagnosing cancer by obtaining secretome from a cell culture from peripheral blood. A non-hematological cell component present in peripheral blood is allowed to expand in the cell culture and a measurement of channel current I(t) at a measurement point is performed in a channel of conductive polymer located between first and second electrodes, the channel being arranged to act as a conducting channel of a transistor and being connected to a gate electrode of the transistor through the secretome. A modulation m, given by final intensity Ids of channel current normalized with respect to initial intensity Ids0, and a time constant ? given by the time it takes for the channel current I(t) to reach a predetermined percentage of the final intensity Ids are obtained. The m and ? values are indicative of protonation state of the secretome and, on the basis of the values, the secretome is classified as being from a healthy individual, an individual having cancer, or an individual at risk for cancer.
