Theoretical command
Check command of mechanotransduction and soft sensor physics: piezoresistive versus capacitive versus ionic transduction, hyperelastic models (Ogden, Yeoh), viscoelastic drift, and cell-material interface mechanics at kPa stiffness.
Evidence to listen for
- Explains the underlying theory at the level the role demands, and can go a layer deeper when pushed
- Knows which results are established and which are contested
- Distinguishes their own contribution from the field's
- Comfortable saying where the theory runs out
Five-point scoring guide
Recites terminology without understanding; cannot go one layer deeper.
Surface familiarity; conflates established results with speculation.
Solid grasp of the core theory; thin at the frontier.
Strong command; separates settled results from open questions.
Derives sensitivity and hysteresis limits from first principles, and names why a given transduction mode fails on living or hydrogel substrates.
