Abstract
The invention provides a method for capturing and analyzing the total electrical response to a time-varying electrical stimulation of a system or device containing electrochemically active biological or non-biological substances. The response can be either a time-varying voltage (in the case of current-mode stimulation), or a time-varying current (in the case of voltage-mode stimulation). Using synchronous data acquisition technology and advanced data analysis, the method yields not only the idealized 2-parameter information (e.g., phase and amplitude) provided by conventional methods, but also parameters extracted from non-ideal features of the response waveform that are suppressed by impedance methods. By extracting the full range of response characteristics, the method yields a multi-parameter representation of the system or device under test. The inventive methods may be embodied in an open-loop form, wherein the results of measurements and analysis are reported to the operator, or in a closed-loop form, wherein said results are fed back to modulate the behavior of the system or device.
