Needle-based injections have revolutionised healthcare by providing an efficient delivery method for medications, such as vaccines. However, there are significant drawbacks associated with using needles on a societal, environmental, and technological level. Needle phobia and infection risks can significantly impact patient compliance and safety with medical treatments, while millions of used needles contaminate the environment every day. Lastly, the effectiveness of certain drugs increases when injected intradermally, but targeting the dermis is challenging. With iSENS, we want to revolutionise the experience of people who receive and perform frequent injections. To this end, we are developing and commercialising a portable and needle-free injector called BoldJet. Through the technological breakthrough we present in this project safer, more effective, and minimally invasive injections that do not contaminate our environment. This patient-friendly technology will result in a positive effect on society, allowing millions of people to receive better and more personalised healthcare.
