Formulation delivery systems, devices, and methods

This is a handheld device designed to precisely apply a liquid formulation, such as a cosmetic or dental material. It features a reusable handle that accepts interchangeable cartridges, one for the formulation and another for cleaning. Inside, a pump pushes the liquid through a nozzle that moves back and forth, and a smart controller authenticates the formulation cartridge before dispensing and manages the device's power.

Why it matters: Since 2022, advancements in compact, low-power microcontrollers and precision micro-actuators have made the integrated control logic and reciprocating nozzle assembly more cost-effective and robust for handheld devices.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateReciprocating nozzle, pump, controller logic, custom cartridges.
