Abstract: A woven structure includes thermoelectric ribbons interwoven with thread. Each thermoelectric ribbon includes a matrix of thermoelectric elements, the matrix having an insulating substrate that supports plural rows of thermoelectric elements, a plurality of conductive elements, and two terminals. The conductive elements form a series connection of the thermoelectric elements between the two terminals. A set of first conductive elements have a first temperature and a set of second conductive contacts have a second temperature lower than the first temperature when a first current flows in a first direction between the first matrix terminal and the second matrix terminal. The matrix is configured to form spaced-apart alternating stacks of the first conductive contacts and second conductive contacts. Each length of the yard or thread is interwoven such that it passes alternately under stacks of first conductive contacts and over stacks of second conductive contacts.

Abstract: A method for preparing a stack of dielectric layer on a substrate. A substrate is provided and a first layer of liquid is printed onto a surface of the substrate. A first dielectric layer is formed by solidifying the first layer of liquid and a second layer of liquid is printed onto the first dielectric layer. A second dielectric layer is formed by solidifying the second layer of liquid. The liquid includes dielectric constituents and the liquid is printed such that droplets having a volume of less than one hundred nanoliters are locally deposited per square millimeter on the surface of the substrate.

Abstract: The invention relates to new conjugated semiconducting polymers containing thermally cleavable side groups. The thermally cleavable side groups are selected from among carbonate groups and carbamate groups. By thermally cleaving side groups, the solubility or the polymers can be reduced in a targeted manner. The polymers are used as semiconductors in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices, organic photodetectors (OPDs), organic light emitting diodes (OLEDs), and organic field effect transistors (OFETs).

Abstract: A thermoelectric system includes a plurality of thermocouples that are each formed of two thermocouple limbs that include different thermoelectrically active materials. The thermocouple limbs are connected electrically in series and thermally in parallel. The thermodynamic system also includes a flexible and electrically insulating layer formed of a matrix having n rows of thermocouple limbs. The thermocouple limbs form columns having approximately equal widths. Each pair of adjacent thermocouple limbs has a contact region located on a straight fold line above one another in the column direction. The matrix is wound parallel to the rows on top of one another to form a flat strip. The matrix is then folded along the fold lines in the manner of a concertina with elevations and depressions equidistant to one another.
