The present disclosure describes energy storage (e.g., electrochemical) devices with customized architectures. Such customized architectures include multilayered electrode films and/or multidimensional electrode films.

Multilayer and/or multidimensional electrode films for energy storage devices, and methods thereof

Disclosed are compositions, devices, systems and fabrication methods for stretchable composite materials and stretchable electronics devices. In some aspects, an elastic composite material for a stretchable electronics device includes a first material having a particular electrical, mechanical or optical property; and a multi-block copolymer configured to form a hyperelastic binder that creates contact between the first material and the multi-block copolymer, in which the elastic composite material is structured to stretch at least 500% in at least one direction of the material and to exhibit the particular electrical, mechanical or optical property imparted from the first material. In some aspects, the stretchable electronics device includes a stretchable battery, biofuel cell, sensor, supercapacitor or other device able to be mounted to skin, clothing or other surface of a user or object.

Hyperelastic binder for printed, stretchable electronics

A multilayer flexible electronics platform is an apparatus that allows modular thin-film electronics to be integrated into everyday flexible, flat objects such as pieces of clothing, material coatings, or wearable devices. The apparatus includes a flexible water-impermeable envelop, a flexible power-source layer, a flexible printed circuit board (PCB) layer, and a flexible accessory-interfacing layer. The flexible accessory-interfacing layer allows those modular thin-film electronics to be electronically and electrically attached to the apparatus. The flexible PCB layer allows the apparatus to control and manage those modular thin-film electronics. The flexible power-source layer is used to provide electrical power to those modular thin-film electronics. The flexible water-impermeable envelop protectively encloses those modular thin-film electronics and the aforementioned functional layers of the apparatus.
