Work on Paper Batteries Charged by Bacteria
- amelius 8y agoMost interesting bit: > In the lab, the microbial battery produced a maximum power of 4 µW/cm2 and current density of 26 µA/cm2, which Choi says are “significantly higher” than previous paper-based microbial batteries. Even so, the power performance is “very low,” limiting their application, at least for now. To be viable for commercial use, the power/current density must be improved by a factor of around 1,000, Choi says.
- snaky 8y agoActually this may be enough for modern IoT sensors, adding capacitor and doing transmission less often helps. Even flashing the LED (5mA pulses for 1ms) is only 5uA on average (once a second, 0.1% duty cycle) or even 1uA (once a 5 second, 0.02% duty cycle).
