Provided are an electronic device employing a polymer nanosheet, having an electronic element and a conductive wiring that are connected to each other in a solder-free manner, and exhibiting a high conformability and adhesiveness to an object for attaching including a biological tissue such as skin; and a method for manufacturing the same. The electronic device includes the electronic element; and the polymer nanosheet adhering to the electronic element. Specifically, the polymer nanosheet adheres to the electronic element in a manner such that one surface of the electronic element is entirely covered by the polymer nanosheet. It is preferred that the polymer nanosheet have a thickness of smaller than 1 &#x3bc;m. Further, a conductive wiring capable of being electrically connected to the electronic element; and a power source for supplying power to the electronic element, may also be formed on the polymer nanosheet.

Flexible electronic device containing electronic element and polymer nanosheet and method for manufacturing same

A self-healing wire includes, an electric wire arranged on a substrate, and a hybrid structure in which the electric wire is covered with at least one fluid selected from the group consisting of a fluid having conductive particles dispersed therein and a fluid having metal ions dissolved therein, formed on a healing portion for a crack to be generated in the electric wire. And a stretchable device includes the self-healing wire formed on a stretchable base material and an electric element mounted only on a base material higher in rigidity than the stretchable base material. Even when a crack is generated in the electric wire due to stretching of the substrate having flexibility, the crack is bridged by the conductive particles or a solid metal deposited from the metal ions in the fluid. Thus the self-healing wire and the stretchable device having both high conductivity and high stretchability are provided.

Self-repairing wiring

Provided is a micro drive unit, which is capable of performing multi-axis drive, the micro drive unit including: a movable object; and at least one pair of beams configured to pivotally support the movable object and formed only in one direction, the movable object being configured to rotate or translate in an x-axis direction, a y-axis direction, and a z-axis direction when the at least one pair of beams is twisted or bent at one or a plurality of resonant frequencies of the at least one pair of beams, thereby being capable of simultaneously avoiding upsizing and complication of the structure. And by incorporating the micro drive unit, a micro device capable of achieving multi-axis drive can be manufactured.
