3D Printed Electronic Skin Could Open the Way for Human-Machine Interaction

The skin is the largest human organ and the largest sensory connection to the rest of the world due to its more than 1,000 nerve endings. This makes it not just incredibly important to humans as they interact with their environments, but also very difficult to replicate, including through 3D printing. However, that may no longer be the case. Researchers at Texas A&M University have developed a 3D printed electronic skin, or e-skin, which they claim can flex, stretch and sense like human skin. The best part? They hope it could be the first step in future human-machine interaction.

Though it may sound like science fiction, calling on endless films and books talking about androids that are indistinguishable from human or life-changing bionic surgeries, this 3D printed electronic skin is undoubtedly reality thanks to the use of hydrogels and 3D printing. Not only that, but it could be very important for a number of applications, including for individuals with disabilities.

Dr. Akhilesh Gaharwar, professor and director of research for Texas A&M’s Department of Biomedical Engineering, explains, “The ability to replicate the sense of touch and integrate it into various technologies opens up new possibilities for human-machine interaction and advanced sensory experiences.” He continues, “The inspiration behind developing E-skin is rooted in the desire to create more advanced and versatile interfaces between technology, the human body and the environment. The most exciting aspect of this research is its potential applications in robotics, prosthetics, wearable technology, sports and fitness, security systems and entertainment devices.”
