    Abstract: Disclosed herein are techniques for drug delivery measurement. A medicine delivery device includes a cartridge for storing a medicine, a needle assembly coupled to a bottom of the cartridge, a piston located in the cartridge for pushing the medicine to dispense the medicine from the cartridge through the needle assembly, and a sensor configured to measure a distance between the piston and the bottom of the cartridge. The sensor includes a triangulation-based distance measurement unit, a resonant frequency-based distance measurement unit, a time-of-flight-based distance measurement unit, or a frequency-modulated continuous-wave time-of-flight-based distance measurement unit.
