Resistance/Reactance/Impedence TRIZ Cases

Externally mounted sensors read dielectric changes through sealed walls to flag contamination, tampering, or liquid degradation without opening containers.

Opposed laser arrays and bonded prism beam splitters help a Rydberg vapour cell distinguish radio frequency and arrival angle while resisting vibration.
