Medical technology is developing much faster than cars and other equipment. The emergence of "smart" needles for syringes was a matter of time, and they were finally created. They were developed by researchers from Brigham Women's Hospital - they made the needles sensitive to tissue pressure. This allows you to make more accurate and painless injections in such vulnerable areas as the eyes and subcutaneous tissue between the skin and muscles.

The prototype was called the “intelligent injector for targeting tissue”, or simply i2T2. Its main component is a sensor for detecting changes in applied pressure when its tip passes through different types of biological tissues with different densities. For example, a needle can quickly determine which layer of the eye it is in. It is expected that this will greatly facilitate the work of doctors since any mistake in the introduction of injections can cause serious problems.

In laboratory tests on animals, I2T2 has proven to be effective in injecting injections into the epidural space adjacent to the spinal cord and into the subcutaneous tissue between the skin and muscles. He also successfully delivered stem cells to the inside of the eye, which is often used in regenerative therapy.
