Establish complete bioresorbable energy-system closure

Establish complete self-powered operation for bioresorbable medical systems by integrating compatible bioresorbable interconnects, rectifiers, power-management circuits, energy storage, functional electronics, and encapsulation with a degradable energy harvester, while sustaining the required therapeutic function and enabling controlled, biologically acceptable degradation.

Background

The review distinguishes a degradable harvester from a fully bioresorbable self-powered medical system. A complete system must include not only the transducer but also compatible interconnects, rectification, power management, storage, functional electronics, and encapsulation.

Preclinical bioresorbable platforms demonstrate progress, but the review explicitly states that complete self-powered operation has not yet been established. The unresolved objective is energy-system closure: sustained operation over the therapeutic interval followed by controlled and biologically acceptable resorption.

A truly bioresorbable self-powered system, however, requires compatible interconnects, rectifiers, PMICs, storage, functional electronics, and encapsulation—not merely a degradable harvester. Although preclinical bioresorbable platforms demonstrate progress [146], complete self-powered operation remains to be established.
