“…This electronic miniaturization means that the sophisticated electronic components used to diagnose the GI system can now be fitted within the size of an ingestible capsule. These new medical devices are used to perform a range of functions in vivo, such as endoscopic monitoring [14], [15] and precision drug delivery [16], [17], as well and can form controllable and ingestible soft robotic devices [18], [19]. However, these electronic components are still constructed out of toxic materials and as such device retention is a major concern as fatalities occur in approximately 2% of all cases of ingestion of electronic capsules [20].…”

The development of green batteries has implications for many fields including sustainable robotics and edible electronics. Here we present GelBat, a biodegradable, digestible and rechargeable battery constructed from gelatin and activated carbon. The device utilises the water splitting reaction to produce a simple, sustainable Bacon fuel cell which can produce an output voltage of over 1V for 10 minutes, depending on the load resistance, with 10 minutes of charging and whose only byproduct is water. Electrochemical impedance spectroscopy, cyclic voltammetry and self discharge tests are carried out to characterize the behaviour of the battery. The system does not lose any efficiency with repeated recharging cycles and can be completely dissolved in a simulated gastric fluid within 20 minutes. The simplicity of this design combined with the bioresorbable materials demonstrates the potential of this work to help advance robotic research towards more sustainable untethered autonomous systems and edible robots.
