Flexible Electrical Biasing for In Situ TEM

The TEM Electrical Biasing Sample Holder enables controlled in situ electrical biasing experiments inside the transmission electron microscope while simultaneously imaging structural, morphological, and functional changes at high spatial resolution. The holder uses a flexible carrier architecture that supports a wide range of experimental configurations, allowing researchers to investigate electrically driven phenomena under realistic operating conditions.

Flexible Chip Carrier Architecture

Unlike fixed chip platforms, the flexible carrier design supports all Hummingbird Scientific electrical biasing chips while also allowing researchers to integrate their own fabricated chips, MEMS devices, sensors, and custom sample geometries. Multiple carrier designs can be developed to accommodate application-specific devices without changing the overall holder platform, providing a flexible foundation for evolving research requirements.

Stable Electrical Measurements

Individually shielded electrical wiring minimizes electrical noise throughout the signal path, while the low-drift sample rod maintains stable positioning during extended experiments. The holder is compatible with analytical TEM techniques including EDS and EELS, enabling simultaneous electrical stimulation with structural and chemical characterization.
