Abstract: The present invention relates to large surface distributed pressure sensors comprising at least two flexible substrates, at least of one of these being entirely or partially coated by a layer of polythiophene containing repetitive structural units with formula (I), wherein R1 and R2 are independently a C1-C12 alkyl group or they form a C1-C12 1,n-alkylene group, with n=1-12, optionally substituted by a C1-C12 alkyl group, C2-C12 alkene, vinylene, benzyl, phenyl group, a halogen atom, or by an ester, amine, amide or ether functional group, optionally substituted by a C1-C12 alkyl group; and one or more insulating spacers. Said sensors are flexible and easy to manufacture and they may present different symmetric, simple or multilayer configurations, as desired.

Abstract: The invention relates to an electrochemical sensor for the detection of analytes in liquid media which comprises 4 layers, wherein the first layer (1) comprises a carbonaceous material deposited on a substrate, said layer forming the system of electrodes of the electrochemical sensor, formed at least by a pseudo-reference electrode, a working electrode and a counter electrode; and the fourth layer (4) comprises polythiophene deposited only on the lower end of the working electrode selected from (d1), which comprises a layer comprising a polythiophene deposited on the lower end of the working electrode and a layer comprising a non-conductive polymer gel deposited on said layer of polythiophene; (d2), which is a layer of conductive polymer gel comprising a non-conductive polymer gel and a polythiophene; and (d3), which comprises a layer comprising a polythiophene deposited on the lower end of the working electrode and a layer comprising functionalized magnetic nanoparticles deposited on said layer of polythioph

Abstract: The present invention relates to a temperature-time indicator system which allows monitoring the maintenance of the cold chain in frozen or refrigerated substances based on irreversible color changes, comprising a layer with a solution of ascorbic acid and a layer with a solution of at least one base, wherein the solution of ascorbic acid does not mix with the solution of at least one base unless the temperature reaches a pre-determined threshold. The invention also relates to a method using said system.

Abstract: The invention relates to a device comprising one left electrochromic filter (3) and one right electrochromic filter (4) controlled by an electronic device (12). Said electronic device has means for controlling at least one filtering parameter, said means being actuatable by the user and programmed by a professional ophthalmologist, or a combination of the two. The aim of the invention is to provide variable filtering for the vision of a user of the device.

Abstract: The invention relates to electrochromic compositions comprising: (a) a viologen derivative of formula (I) (b) an electron mediator; (c) a polymer compound of formula (II) (d) a plasticizer of formula (III): and (e) a mixture of at least two miscible solvents which dissolve components (a) to (d) at room temperature, at least one of them being a solvent with a high boiling point. Said electrochromic compositions can be formulated and applied at room temperature, therefore they allow preparing electrochromic devices with heat-sensitive substrates, particularly with fully plastic substrates, with a high degree of transparency and with a high optical contrast.

Abstract: This mini fuel cell battery has a central body into which two membrane electrode assemblies are positioned, one at each end of the central body. An anodic space is defined between the two membrane assemblies. The central body has two internal threads into which two externally threaded rings are screwed in to seal the membrane assemblies in the central body.
