Energy storage silk implant

Are energy storage implants biocompatible?

Existing energy storage implants grapple with balancing factors such as high performance, biosafety, mechanical properties matching soft tissues, and conformal adhesion. Herein, we report a thin, flexible, and wet-adhesive zinc-ion hybrid supercapacitor (ZHSC) as an implantable power source with high biocompatibility and superior performance.

What is pure silk?

Pure silk is innovatively employed, which is known for its excellent biocompatibility, to engineer water-triggered, geometrically reconfigurable membranes, on which functions can be integrated by Micro Electro Mechanical System (MEMS) techniques and specially functionalized silk.

Can silk fibroin-based ion-exchange membranes power implanted medical devices?

Powering implanted medical devices (IMDs) is a long-term challenge since their use in biological environments requires a long-term and stable supply of power and a biocompatible and biodegradable battery system. Here, silk fibroin-based ion-exchange membranes are developed using bionics principles for reverse electrodialysis devices (REDs).

Can Silk sericin be implanted based on a piezoelectric principle?

To address this demand, it is proposed utilizing a natural biomaterial, silk sericin (SS), which exhibits valuable biological activities and contains abundant asymmetric amino acids with adjustable structures, to create an implantable self-powered system based on the piezoelectric principle.

Do functional bioelectronic implants need energy storage modules?

Functional bioelectronic implants necessitate energy storage modules as power sources in vivo. Existing energy storage implants grapple with balancing factors such as high performance, biosafety, mechanical properties matching soft tissues, and conformal adhesion.

What is a stretchable energy supply device for implantable electrical stimulation?

Yuan et al. proposed a stretchable, rechargeable energy supply device for implantable electrical stimulation (Fig. 3 d). This innovative device incorporates a stretchable energy-receiving coil, conductive wiring, and supercapacitor current collectors, all fabricated using liquid metal components integrated onto an elastic substrate.
