Scientists have developed a fuel cell that uses microbes in soil to produce electricity. The device can power underground sensors for tasks like monitoring moisture or detecting touch, without needing batteries or solar panels. It works in both dry and wet conditions and even lasts longer than similar technologies. This could pave the way for sustainable, low-maintenance sensors in farming and environmental monitoring.
