Artificial skin can be used to feel virtual, augmented reality – Review Geek

Swiss researchers have developed a new artificial skin that can potentially be used in combination with virtual and augmented reality systems to allow wearers to feel their digital environment through haptic feedback

The & # 39; skin & # 39; is described as soft, flexible and durable thanks to the fact that it is made of silicone and flexible electrodes. It can be stretched to four times its original length for a million cycles, giving it the power it needs for real applications. According to lead research author Harshal Sonar, this is the first development of its kind in which both sensors and actuators are integrated.

Haptic feedback is provided by pressure and vibrations thanks to soft pneumatic actuators that can be inflated up to 1

00 times per second. The artificial skin vibrates when quickly inflated and deflated. Sensors in the skin can detect distortions and adapt to the wearer's movements, as well as changes in external factors. The device continuously measures stimulation and adjusts it in real time to replicate the sensitivity of human touch.

The first tests were conducted with a small implementation that can be worn on a person's finger, although Sonar says the next step is to develop a "fully portable prototype" for wider scenario & # 39; s for usage scenario & # 39; s. Along with possible applications to improve the immersion of virtual and augmented reality, it is thought that the creation could be used for medical rehabilitation such as testing the proprioception of a patient (sense of self-movement and posture).

"It can be used to stimulate the human body while researchers study dynamic brain activity in experiments with magnetic resonance," Sonar said. "This gives us a closed loop control, which means that we can accurately and reliably modulate the vibration stimulation that the user feels."
