A wireless, high-resolution galvanostat is fabricated using "smart dust" technology for under $100 dollars using free software and general use hardware. We demonstrate a design that uses either PWM or DAC to set a current with up to 100-picoampere resolution for any value between -15 and 15 mA. An ADC measures the potential of a battery during charge cycles using a short (∼400 μs) interrupt. The device performs well when tested against calibrated values for a variety of capacitors and resistors. copyright The Electrochemical Society.
