Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate

open access: yesAdvanced Functional Materials, EarlyView.
Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.
