Researchers have learned to print biosensors directly on internal organs

Some people urgently need constant monitoring of their internal organs. For this, there are various equipment that a person must carry on himself. However, this is not always convenient and can cause discomfort. An alternative may be biosensors directly on the internal organs. American researchers just introduced the appropriate technology of 3D printing.

University of Minnesota employees have developed a new 3D printing method that allows sensors to be applied directly to internal organs. A particular difficulty lies in the fact that the heart and lungs are constantly in a mobile state and change shape. To solve this problem, the “motion capture” technique was widely used in the production of films and video games. With its help, the printer is able to monitor the trajectory of printing on the surface of organs, depending on the change in their shape.

This technology has already passed the first successful tests. Using a 3D printer, scientists were able to print a sensor made of a soft hydrogel on the surface of a light pig. The use of such biosensors should greatly simplify the monitoring of such important organs as the lungs and heart. With their help, doctors will be able to obtain more accurate information about the patient’s condition in real time.
