Electrical techniques are experimental or analytical methods that apply controlled electric fields, currents, or potentials to probe, manipulate, or characterize physical, chemical, or biological systems. They encompass approaches such as impedance spectroscopy, voltammetry, electrophysiology, and conductive or dielectric measurements, enabling quantification of parameters like conductivity, permittivity, charge transport, interfacial kinetics, and membrane potentials. These techniques often rely on precise instrumentation for signal generation and detection, including amplifiers, electrodes, and shielding to minimize noise. Electrical techniques are integral in material characterization, sensor development, electrochemical analysis, and the investigation of ion channels, neural activity, and other bioelectrical phenomena.
Inside the California NanoSystems Institute at UCLA, where some of the most advanced and technical automated infrastructure on campus resides, two students saw an opportunity hiding in plain sight.
