Abstract: An acoustic device (100) comprises an array of acoustic transducers (10a,10b) formed by a patterned stack (12-15) on a flexible substrate (11). The stack comprises a piezoelectric layer (13) sandwiched between respective bottom and top electrode layers (12,15), and a patterned insulation layer (14) formed by a pattern of insulation material (14m). The pattern comprises insulated areas (A14) where the insulation material (14m) is disposed between one of the electrodes (12,15) and the piezoelectric layer (13), and contact areas (A10) without the insulation material (14m) where both electrodes (12,15) contact the piezoelectric layer (13).

Abstract: A collimator filter (10) comprises an entry surface (11) to receive incident light (Li, Li?) at different angles of incidence (?i, ?i?) and an exit surface (12) to allow output light (Lo) to exit from the collimator filter (10). A filter structure between the entry surface (11) and the exit surface (12) transmits only parts of the incident light (Li) having angles of incidence (?i) below a threshold angle (?max). The filter structure comprises a patterned array of carbon nanotubes (1), wherein the nanotubes (1) are aligned extending in a principal transmission direction (Z) between the entry surface (11) and the exit surface (12). The nanotubes (1) are arranged to form a two dimensional pattern (P) transverse to the principal transmission direction (Z). Open areas of the pattern (P) without nanotubes (1) form micro-apertures (A) between the nanotubes (1) for transmitting the output light (Lo) through the filter structure.

The electro-optical unit further has first (12), second (13) and third (14) control terminals, wherein the photodiode (2) and the programmable resistive element (4) are coupled in series between the first (12) and third (14) control terminals and M wherein the light emitting diode (3) and the programmable resistive element (4) are coupled between the second (13) and third (14) control terminals. One electrode (2a/2c) of the light-emitting diode, one electrode (3a) of the photodiode and a terminal (4a) of the programmable resistive memory element are connected in common at a node (5).

Abstract: A light-emitting device comprising an anode; a cathode; a light-emitting layer arranged between said anode and said cathode; and a buffer layer, comprising a conducting polymer and a polymeric acid, arranged between said anode and said light-emitting layer, is disclosed. Acidic groups of said polymeric acid have been converted to non-acidic groups in at least a part of said buffer layer, which minimises acid quenching of photoluminescence. A method for manufacturing such a device is also disclosed.

Abstract: A polymer comprising structural units of the formula I is prepared according to a novel method, in which the starting compound R1 ‘S—(CHR’2)—Ar—(CHR2)—SR1 is polymerized with a base, preferably in an aprotic solvent. The polymer comprises 50 to 1000 structural units of the formula I. The solution comprising the polymer thus prepared has a lower viscosity than a solution of a similar polymer with a greater chain length. The solution comprising the polymer thus prepared may be applied as a layer on a substrate. Electronic components with layers prepared with the polymer of the invention show better properties.
