Scientists are developing self-healing robots that can feel pain, sense damage, and even repair themselves without any human intervention. The soft robotic hands are made through 3D printing and able to carry out a wide variety of applications, from grabbing delicate and soft objects in the food industry to performing minimally invasive surgery. They could also play an important role in creating lifelike prosthetics. However, the soft materials also make them susceptible to damage from sharp objects or excessive pressure. But now researchers have developed new polymers that can heal themselves, by creating new bonds in 40 minutes, with the end goal making the healing automated.
