AC dielectric cure monitoring, also referred to as Dielectric Analysis (DEA), measures a polymer’s capacitance and resistance, which are bulk properties utilized in the conventional electrical model ...

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...

There are many secondary functions associated with designing an electrocardiogram (ECG) signal chain, but one of the most important might be the most underrated: making sure that the electrodes are ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...
