# Binghamton develops hydrogel biobattery inspired by intestinal villi

> Binghamton researchers built a biobattery using Bacillus subtilis bacteria in hydrogel structures inspired by intestinal villi. With a continuous nutrient supply, the experimental device sustained about 0.75 volts for at least 14 hours, indicating potential for small LEDs and microsensors.

An ion-exchange membrane separates the hydrogel anode from a carbon-cloth cathode. The three-dimensional architecture aims to improve nutrient transport and available bacterial surface. Wastewater-pipe use and scalable single-step printing are future goals; the research does not report an installed wastewater power system.
