Publication number: 20220202333Abstract: The invention provides a composition for a conductive polymeric material suitable for the production of electrodes for recording electrophysiological signals, such as electrocardiogram (EGG), electromyogram (EMG), electroencephalogram (EEG), etc and signals related to the impedance variation of the body or skin, both deriving from active and passive measures (for example, breathing, electrodermal response, etc.). For this purpose a formulation containing FEDOT and ionic liquids has been developed. The formulation according to the invention can be used generically in the context of detecting bioelectric signals and can be applied on wearable items, in particular in fabric, such as for example garments of different shapes, so as to be in direct contact with the areas of the body subject to detection.Type: ApplicationFiled: April 29, 2020Publication date: June 30, 2022Inventors: Giuseppe Arnaldo USAI, Erika SCAVETTA, Isacco GUALANDI, Beatrice FRABONI, Marta TESSAROLO, Annalisa BONFIGLIO, Danilo PANI, Eleonora SULAS

Patent number: 11360046Abstract: The present invention relates to an organic electrochemical transistor based on conducting polymers (for example PEDOT:PSS) in which the gate electrode has been integrated on the surface of the channel through the deposition of Ag halide nanoparticles, AgX (X?CI, Br, I). This configuration allows the device to operate without applying a potential difference to the gate electrode (with consequent reduction in operating costs). The device is able to detect the halide ion: by varying the nature of the nanoparticles and in particular by using AgX (X?CI, Br, I) or Ag2S the sensor acquires sensitivity towards anion X or sulfide.Type: GrantFiled: April 23, 2018Date of Patent: June 14, 2022Assignee: ALMA MATER STUDIORUM—UNIVERSITA' DI BOLOGNAInventors: Erika Scavetta, Beatrice Fraboni, Isacco Gualandi

Publication number: 20220022815Abstract: A sensorized garment is provided. The sensorized garment includes an wearable element on a skin having a hand-tightening or a closure device to securely constrain sensors, for example electrodes to detect electrophysiological signals, during a physical activity. The wearable element has a three-dimensional shape to uniquely define a right side and a left part of a circumferential zone when the wearable element is worn. The sensorized garment further includes a band carried by the circumferential zone, and at least one conductor connected between the sensor and a zone of the sensorized garment.Type: ApplicationFiled: December 5, 2019Publication date: January 27, 2022Applicants: LET'S - WEBEARABLE SOLUTIONS S.R.L.

Patent number: 5191213Abstract: The structure of a multilayered integrated circuit is determined by removing successive layers of the circuit. Following removal of each layer, the revealed surface is scanned by an electron beam. The intensity of backscattered or secondary electrons is detected by a first or second detector respectively. From the detected electron intensities, image processing circuitry derives a representation of the integrated circuit surface scanned. Where the surface of the integrated circuit is a flat layer of semiconductor substrate material having implanted doped areas, the surface is covered with a metallisation layer providing a Schottky barrier junction with the doped areas. Electron beam scanning of the metallisation layer induces a current at this junction which is monitored and processed to derive a representation of the outline of the doped implanted areas.Type: GrantFiled: July 5, 1991Date of Patent: March 2, 1993Assignee: Olivetti Systems & Networks S.r.l.Inventors: Haroon Ahmed, Simon Blythe, Beatrice Fraboni
