Electronically-Controlled Meshless Pocket-Size Ultrasonic Inhalers

  • First, we describe: (1) the architecture of our silicon-based MFH nozzle and its excitation of megahertz (MHz) Faraday waves in the liquid (medicine) layer sitting on the nozzle end face, and (2) the requisite drive power for droplet ejection and drive frequency for desired droplet diameter.
  • Second, we present data demonstrating the realization of low-drive power pocket-size prototype inhalers and their uses for nebulization of a variety of common and experimental pulmonary drugs with desirable aerosol characteristics.
  • Finally, we discuss the new inhaler’s additional unique capabilities, including simultaneous aerosolization of multiple drugs for combination therapy and the potential for incorporation of IOT technology for enhanced functionality.
