An electronic device is described that is designed to be more easily recycled at its end of life while maintaining usability during its lifetime. The electronic device includes a first substrate, an encapsulation layer, and a set of electronics disposed there between. One or more delamination layers cover at least one side, preferably both sides, of the set of electronics to separate the set of electronics from at least one, preferably both, of the first substrate and the encapsulation layer. The set of electronics, covered by the one or more delamination layers, is encapsulated between the encapsulation layer and the first substrate. At least one of the delamination layers includes a set of passages filled with material of the encapsulation layer forming a set of interconnections between the encapsulation layer and the first substrate.

Recyclable electronic device

A printed temperature sensor () comprising a substrate () with an electrical circuit () comprising a pair of electrodes () separated by an electrode gap (G). A sensor material () is disposed between the electrodes () to fill the electrode gap (G), wherein the sensor material () comprises semi-conducting micro-particles () comprising an NTC material with a negative temperature coefficient (NTC), wherein the micro-particles () are mixed in a dielectric matrix () functioning as a binder for printing the sensor material (); wherein the micro-particles () contact each other to form an interconnected network through the dielectric matrix (), wherein the interconnected network of micro-particles () acts as a conductive pathway with negative temperature coefficient between the electrodes ().

Printed temperature sensor

The invention relates to a method for preparing a composition for coating, wherein a layered, inorganic filler is subjected to an ion exchange with a modifier, which modifier comprises at least two ionic groups, which groups are separated from each other by at least four atoms, and wherein the modified filer, together with a polymer, is dispersed in a diluent.
