Portal Instruments Selects CAP-XX Supercaps for Needle-Free Jet Injection Platform

CAP-XX’s ultra-thin prismatic supercapacitors, manufactured in Australia and Malaysia, deliver burst power needed for high-speed needle-free jet injection

Sydney, Australia – March 15, 2021 – CAP-XX Limited (LSE:CPX), the leading manufacturer of ultra-thin prismatic and cylindrical supercapacitors, announced that Portal Instruments, a clinical stage medical device company, has selected the CAP-XX GS230F supercap for its advanced needle-free drug delivery platform for self-administering biological medicines. Portal Instruments chose the CAP-XX prismatic supercapacitors, which are manufactured in CAP-XX’s production facilities in Australia and Malaysia, due to their characteristic low ESR which enables the high burst of energy needed to drive the fast, large volume needle-free jet injection, and for their thin form factor which fits easily inside the small drug delivery device.

Portal Instruments’ needle-free jet injection platform is intended to simplify the drug delivery experience, from self-injection for patients suffering from chronic disease, to healthcare workers delivering vaccines. The handheld connected device delivers injectable medications without a needle by pressurizing the drug itself, which passes through a 160 µm nozzle to create a very fine fluid jet, about the size of a hair, at a controlled speed. This jet pierces the skin, delivering the drug to the target tissue in a fraction of a second, up to 30x faster than a conventional autoinjector and with less pain. Portal’s platform can deliver injection volumes up to 2 mL, irrespective of drug concentration and viscosity.

Portal Instruments uses multiple ultra-power-dense CAP-XX GS230F supercapacitors to deliver hundreds of watts of output power to drive the high-speed, concentrated injection in its compact handheld device. CAP-XX’s industry-leading power density enables the device’s small, easy-to-use form factor and allows the device to operate from a compact, industry-standard rechargeable battery which recharges the supercapacitors before every injection.

The CAP-XX GS230F supercap features:

  • 1200 mF
  • 5 V
  • 39 x 17 x 3.9 mm
  • Very very low ESR of 25 mΩ which is critical in this fast drug delivery application
  • Very low leakage current 2.5 µA (micro-Amps)

“Our vision is a needle free world,” said Patrick Anquetil, Portal Instruments’ CEO.  “The CAP-XX supercapacitor is a key enabler in delivering a fast, concentrated injection that is over within half a second, empowering the patient to more comfortably manage their chronic condition.”

“We are proud to provide the high-density power Portal Instruments needs to inject high viscosity biologics without the pain and anxiety of needles,” said Anthony Kongats, CEO at CAP-XX. “Their needle-free breakthrough technology can bring welcome relief to self-injecting diabetic, arthritis and IVF patients, and mass vaccination sites around the world. This is just one example of the many possible applications for thin CAP-XX supercapacitors in medical devices.”
