A flexible antenna that follows the device body enables compact drug delivery hardware with simpler integration and reliable wireless data transfer.

Stamped metal plunger bodies overmolded with plastic create a hollow rod that supports spring tuning for different drug viscosities.

A stamped metal plunger body with plastic overmolding balances spring force, energy input, and structural integrity for higher-viscosity drugs.

Sensor-triggered clutch locking limits the maximum dialed dose in an injection pen, reducing user errors while keeping dose setting simple.

A nested cycloidal and planetary drive boosts gear ratio and torque in a compact drug delivery mechanism while supporting precise dosing.

A weighted self-righting support keeps elongated medicament delivery devices upright for mixing and priming, reducing gas-driven dose loss and roll damage.

Pressure feedback and motor-driven plunger control keep cell injection volume consistent and automatically detect occlusions.

Axially spaced ribs keep plunger contact area stable under high extrusion loads, reducing friction variability in viscous drug delivery.

A staged membrane mechanism uses cartridge pressure to assist rupture, cutting manual activation force without bulky springs or levers.

A latching device and setting spring enable stepless injection speed control for thin needles and high-viscosity liquids without added mechanism bulk.

Capacitive skin detection limits needle release to proper body contact, preventing accidental medication expulsion and user injury.

Capacitive skin detection blocks needle deployment on hard surfaces, preventing accidental injection and user injury.

Capacitive sensing is tuned to recognize bare skin while rejecting fingers, clothing, and hard surfaces, so the needle deploys only at the injection site.

A capacitive sensor around the needle opening confirms skin contact before activation, preventing false triggers on hard surfaces.
