"1.5 by 2 centimeters... 0.7 volts... 150 hours... scalability... connected three pieces of the power-generating fabric together and placed them into a 3D printed case that was the size of a standard AA battery... voltage 1.96V—higher than commercial AA battery... power small electronic devices such as an alarm clock... convenience of obtaining commercially available raw materials as well as the low fabrication cost of about $0.15 per square meter make the MEG device suitable for mass production"
