CASE ANALYSIS
Scenario
An Apple Watch biosensor requires electrochemical impedance spectroscopy to characterize electrode-tissue interface. A precision amplifier measures nanoamp currents while a frequency sweep generator probes multiple frequencies.
Key decisions
- Adopted three-electrode potentiostat topology
- Modeled electrochemical cell as Randles circuit
- Used a transimpedance amplifier with gain resistor for current-to-voltage conversion
When to reuse this
Suitable for any low-current AC impedance measurement in wearable biosensors, corrosion monitoring, or battery health assessment.
