Cyclic Voltammetry (CV)

Cyclic voltammetry refers to one type of voltammetry technique used in the fields of electrochemistry, inorganic chemistry, organic chemistry, analytical chemistry, and biochemistry. In cyclic voltammetry, the potential of a working electrode (WE) versus a reference electrode (RE) is ramped linearly with time. After the set potential is reached, the potential across two electrodes (WE v.s. RE) is ramped in the opposite direction to return to the initial potential. These cycles in potential variations could be repeated as many times as required. The analytical data for a cyclic voltammetric experiment comes in the form of a cyclic voltammogram, which plots the current (vertical axis) versus the potential of the working electrode (horizontal axis) during the potential scan. As the Elite-EDC functions as a wireless potentiostat, the voltage across the WE and RE is swept over a pre-set range with a specified sweeping speed. The corresponding current at the counter electrode (CE) is then measured and displayed versus voltage in real-time.

Corrosion (LSV)

Linear sweep voltammetry (LSV) is a fundamental method for characterizing electronic components and materials. Simply connect the Elite EDC with the substance to be determined to start the LSV test.

Material Science

Device I-V Curve

Device I-V Curve, measuring how the current flowing through a device (I_in) changes with the voltage across the device (V_out) has been a fundamental method for characterizing a device (e.g. resistors, diodes, transistors, biosensors, etc.). The I-V curve of a device refers to plotting the measured current versus voltage in a diagram. For a novel device, it is crucial to develop an analytical model for the I-V curve, so as to apply the device as a sensor or to develop a functional circuit with the device.

Charge-Discharge Testing (Constant Current)

The charge-discharge testing of batteries is a standard method used to evaluate the performance and cycle-life of batteries. Typically, the charge-discharge process is conducted at a constant current until a set voltage is reached, and the process will be repeated until batteries deteriorate. As the Elite is lightweight and wirelessly-controlled, it is particularly suitable for long-term monitoring in an isolated, condition-controlled chamber (e.g. a glove box).

Engineering

Device I_ds-V_gs Curve

Device I_ds-V_gs Curve refers to measuring the drain current (I_ds) with varied gate voltages (V_gs). The voltage applied across the gate and source terminals (V_gs) controls the current between the drain and the source terminals (I_ds). The I_ds-V_gs curve can be plotted by measuring the transistor with two Elite-EDC. One Elite will connect with terminals of drain and source of this transistor, and monitoring the current values (I_ds) at a constant voltage applied across them (V_ds). The other Elite will connect with terminals of gate and source to apply varied V_gs. Combining the measuring results from two Elite-EDC can plot the I_ds-V_gs curve to study the behaviors of drain current under different V_gs.

Device I_ds-V_gs Curve

Device I_ds-V_gs Curve. Measuring the drain current (I_ds) vs. drain-to-source voltage (V_ds) with different gate voltages (V_gs) is a typical method for study the linear and saturation region and other characteristics of a transistor. The I_ds-V_ds curve with varied V_gs can be plotted by measuring the transistor with two Elite-EDC. One Elite will connect with terminals of drain and source of this transistor, and recording the current by varying the voltage. The other Elite will connect with terminals of gate and source to apply different V_gs. Combining the measuring results from two Elite-EDC can plot the I_ds-V_ds curve at different V_gs in a diagram.

Electrical Property Measurement

Resistance, Current, and Voltage Monitoring

Monitoring the resistance, current, and voltage of a sample continuously is crucial for investigating the aging effects of various materials, as well as for charaterizing the properties of different thin films (polymer, semiconductors, etc.). This function is also useful for monitoring sensory responses in wearable devices or in unmanned, harsh environments. As the Elite is lightweight and wirelessly-controlled, it is particularly suitable for long-term monitoring in an isolated, condition-controlled chamber (e.g. a glove box).
