For decades, science fiction has imagined electronic devices that spring to life on demand, function as programmed, and then vanish without a trace. Today, transient bioresorbable electronics are making vision reality, sparking revolutionary progress in biomedicine, environmental stewardship, hardware security. Yet one critical barrier remains: fully power source with the same disappearing act. Microbial-based biobatteries have emerged strong contenders, harnessing of microorganisms-found virtually everywhere-as natural biocatalysts. However, toxicity health risks limited these systems single-use, often incinerable applications. Here, transformative approach: biobattery powered by commercially available probiotics dissolves harmlessly is introduced, releasing only beneficial microbes. Fabricated water-soluble or pH-responsive substrates, this capitalizes 15-strain probiotic blend generate electricity across diverse electrode materials. By manipulating device length encapsulating it pH-sensitive polymers, delivery can be fine-tuned from 4 min up over 100 min. A single module outputs µW power, 47 µA current, an open-circuit voltage 0.65 V. This groundbreaking design ushers new era safe, effective bioenergy systems, opening unprecedented opportunities biomedical implants, sensors, disposable electronics.
