Abstract
An electrochemical apparatus includes an array of pixels disposed on a chip, stimulator circuitry disposed on the chip and configured to provide electrical input signals to cause stimulation of the pixels of the array, and sensor circuitry disposed on the chip and configured to read electrical output signals from the pixels of the array. The stimulator circuitry is configured to provide the input signals to cause stimulation of the pixels individually, and the sensor circuitry is configured to selectively read the output signals from the pixels while the pixels are being stimulated. The sensor circuitry is configured to measure an open-circuit voltage at each of the pixels and a current flow at each of the pixels while the pixels are being stimulated by the stimulator circuitry. The open-circuit voltage may be measured while the current flow is being measured.
