The 31-year-old patient’s severe injury was causing double vision and impaired the symmetry and aesthetics of his eyes. Prior to the surgery at the Galilee Medical Center, doctors created a 3D model of the patient’s skull and designed and printed out a titanium plate made according to his CT imaging. During the surgery, one of the surgeons wore Microsoft HoloLens augmented reality glasses that projected the software model of the skull and plate onto the patient’s head. This enabled him to place the real-life plate in perfect overlap with the model. The operation lasted 1.5 hours and the patient went home within a few days. “The innovative technology utilizing a 3D printer and augmented reality resulted in both a particularly accurate execution of the operation and a significant reduction in time,” says the Galilee Medical Center’s Dr. Samer Srouji, who led the surgery. “This technology will contribute to improved clinical outcomes and reduce repeated imaging and surgeries. We feel great pride to be at the forefront of and lead in this global technology,” he added. To read the original article click here. For more articles from Israel21c click here.

This gives us closed-loop control, which means we can accurately and reliably modulate the vibratory stimulation felt by the user. This is ideal for wearable applications, such as for testing a patient’s proprioception in medical applications.” Just like our senses of hearing and vision, our sense of touch plays an important role in how we perceive and interact with the world around us. And technology capable of replicating our sense of touch – also known as haptic feedback – can greatly enhance human-computer and human-robot interfaces for applications such as medical rehabilitation and virtual reality. Scientists at EPFL’s Reconfigurable Robotics Lab (RRL), headed by Jamie Paik, and Laboratory for Soft Bioelectronic Interfaces (LSBI), headed by Stéphanie Lacour at the School of Engineering, have teamed up to develop a soft, flexible artificial skin made of silicone and electrodes. Both labs are part of the NCCR Robotics program. The skin’s system of soft sensors and actuators enable the artificial skin to conform to the exact shape of a wearer’s wrist, for example, and provide haptic feedback in the form of pressure and vibration. Strain sensors continuously measure the skin’s deformation so that the haptic feedback can be adjusted in real time to produce a sense of touch that’s as realistic as possible. The scientists’ work has just been published in Soft Robotics. Haptics Sandwiched Between Silicone Layers The artificial skin contains soft pneumatic actuators that form a membrane layer which can be inflated by pumping air into it. The actuators can be tuned to varying pressures and frequencies (up to 100 Hz, or 100 impulses per second). The skin vibrates when the membrane layer is inflated and deflated rapidly. A sensor layer sits on top of the membrane layer and contains soft electrodes made of a liquid-solid gallium mixture. These electrodes measure the skin’s deformation continuously and send the data to a microcontroller, which uses this feedback to fine-tune the sensation transmitted to the wearer in response to the wearer’s movements and changes in external factors. The artificial skin can be stretched up to four times its original length for up to a million cycles. That makes it particularly attractive for a number of real-world applications. For now the scientists have tested it on users’ fingers and are still making improvements to the technology. “The next step will be to develop a fully wearable prototype for applications in rehabilitation and virtual and augmented reality,” says Sonar. “The prototype will also be tested in neuroscientific studies, where it can be used to stimulate the human body while researchers study dynamic brain activity in magnetic resonance experiments.” To read the original article click here.
