The present invention relates to a stretchable pressure sensor array, comprising: a sensor sheet including an elastic body; a plurality of conductive pillars at least partially embedded in the sensor sheet and formed by aligning magnetic particles in a thickness direction of the sensor sheet; an upper electrode formed on the sensor sheet; and a lower electrode formed under the sensor sheet, wherein when pressure is applied from the upper or lower surface of the sensor sheet in the thickness direction, a conductive path is formed between the upper and lower electrodes and the conductive pillar so that current flows.

A strain sensor according to the present disclosure includes a flexible substrate, a rigid pattern on a side of the flexible substrate, and a conductive flexible pattern extending in a first direction on a side of the flexible substrate, in which the conductive flexible pattern overlaps the rigid pattern such that as the flexible substrate is compressed or stretched, the conductive flexible pattern is compressed or stretched, thereby changing electric resistance.

Manufacturing method of strain sensor, strain sensor and motion sensing apparatus using the strain sensor

Provided is a method of fabricating an organic light-emitting device. The method of fabricating an organic light-emitting device includes: providing a substrate; forming a control electrode on the substrate; forming an insulating layer covering at least a top surface of the control electrode; forming a hole transport layer pattern through printing on at least a part of the insulating layer; forming an organic light-emitting layer to be in contact with at least a part of a surface of the hole transport layer pattern; forming an electron transport layer pattern through printing to be in contact with at least a part of a surface of the organic light-emitting layer; and forming a first electrode and a second electrode respectively on the hole transport layer pattern and the electron transport layer pattern.
