Claims8
A customized stretchable wearable device comprising:
- a stretchable wearable substrate which is worn on an irregularly curved surface;
- and
- a plurality of modularized flexible electronic blocks which are attached to the stretchable wearable substrate in a chemical or physical coupling manner, and of which sizes, arrangement shapes, and arrangement positions are adjusted to correspond to a characteristic of the irregularly curved surface on which the stretchable wearable substrate is worn,
- wherein a size or shape of each of the modularized flexible electronic blocks is adjustable by forming the modularized flexible electronic blocks to have a grid structure in which a plurality of flexible electronic block elements each having a predetermined shape and size are symmetrically disposed and cutting the flexible electronic block elements arranged to have the grid structure into a specific number,
- wherein each of the modularized flexible electronic blocks is chemically coupled to the stretchable wearable substrate through covalent bonding.
