In the search of more sustainable solutions and environmentally conscious forms of energy, researchers are using unconventional materials that push the boundaries of what we can understand about power systems. One such innovation comes from researchers at Binghamton University, who have developed a biodegradable battery using probiotics. This is a breakthrough that may have a paradigm shift in the field of designing transient electronics, where a dissolvable power source can be designed that can be discarded safely into water. 

Probiotic-Powered Battery: The Discovery 

Led by Professor Seokheun Choi, the research team engineered a biodegradable battery with a unique biological component: Bacillus subtilis, a probiotic microorganism commonly found in the human gut. This living cell plays a central role in the functionality of the device, contributing to ion conductivity by forming a natural biofilm structure. 

The battery itself is composed of all biodegradable components, which consists of paper, non toxic metals such as zinc and manganese and the probiotic culture. It produces around 0.2 volts of electricity and dissolves in water within several weeks, making it an ideal candidate for low-power, disposable paper battery applications or temporary medical implants. 

How It Works 

The bacteria are sandwiched in-between conductive electrodes on a paper substrate. The bacteria break down and assists in creating a flow of currents as they break down and when the materials become wet they break down slowly too. This mechanism not only ensures safe disposal but also reduces the environmental impact typically associated with recycling conventional battery materials. 

The team measured voltage output, stability and degradation rate under different conditions in order to evaluate performance. The results confirmed the feasibility of microbial fuel cells as a core power source for next-generation, transient energy systems. It also aligns with developments in zinc-ion batteries, paper-based batteries, and eco-friendly biodegradable battery systems.

Future Applications and Directions 

The development of a dissolvable, bio-based battery opens the door to a range of applications: 

In the future, researchers are developing methods to enhance the energy density and use life span. Improvements in design scalability and controlled degradation will also be key to real-world deployment, particularly in fields aligned with zinc–carbon battery and zinc-metal battery chemistry innovations.
