- 3D printing serves as an essential tool towards fabricating customized implants catering to individual needs. Where implant materials must conform to stringent compatibility norms, adding a different material for each function entails cumbersome and expensive testing, and at the same time increase the risk and discomfort to the user. For example, it is ideal to have a human stent, that is - i) small enough to pass through the blood vessels before it reaches the desired location, ii) expandable at its final location, iii) strong enough to avoid closure of the arteries, iv) able to sense the closure of the arteries during its service, v) self-repairable to avoid repetitive surgeries, vi) conforming to the dimensions of each patient. As of now, a single stent cannot cater to all these functions. In our work, we resolve four of the six above-mentioned constraints. We have designed a new material which exhibits shape memory and piezoelectric behaviour and is 3D printable. We developed and 3D printed a nanocomposite of PLA with piezoelectric barium titanate to create actuators that can feel. We forsee a broad range of applications in the field of robotics and biomedicine for our multifunctional materials.
