A sensor buried in a farm field has two ways to stay powered. A battery that will die. Or a solar panel that will get caked in mud and go dark at sundown. Neither option is good, and both require ...

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 ...

Remote monitoring systems are expanding across sectors, but powering them in off-grid locations remains a challenge. Direct methanol fuel cells (DMFCs) are emerging as a reliable, low-maintenance ...

A new soil-based battery uses microbes to generate electricity, potentially offering a safer and lower-maintenance way to ...
