Are you a doctor? Or a planner for a healthcare marketing career? Wait a moment. What if you introduced a computer application, but, in the present or the near future, to get the professional or healthcare-related service you hope to provide? It will. The future of technology will eliminate the need for physicians and medical marketing in a few decades.
Do you agree? Isn’t it? What do you think about this future technology? Here is some evidence that we are reshaping the world based on our technology.
Today, robots are used for many purposes. That is why the study of this electronic skin is so important. If your robot can help you with homework or medical treatments, Tactile Sense will be a crucial component of its safety function.
It must be able to detect when a surface is slippery, as well as the shape of the objects it captures, the nature of the surface, and the temperature. If the robot can understand the properties of the object, the robot can decide how much force to apply when holding it.
The use of Distributed Sensors to measure pressure changes has attracted the attention of manufacturers and enthusiasts of wearable technology. Artificial electronic skin(or e-skin) has to potential to be used for body health monitoring and internal surgery, as well as for robotics and prosthetics.
It will be a big breakthrough for electronic skin when it incorporates capabilities that are as soft and flexible as human skin. The soft and comfortable electronic skin has a superior ability to handle objects and will remove many of the inconveniences and obstacles associated with current options. It will also mark an important step towards the use of wearable technology.
Electronic skin has softness, flexibility, and elasticity
However, this is a huge challenge. For the skin to conform to the curved surface, flexibility properties must be added to the electronics technology, and the microelectronic technology currently in use is still developed only for flat surfaces. Different approaches and plans are followed to avoid this problem. Early attempts to obtain flexible electronic skin were made by following a flexible printed circuit board path. Here, passive sensors and electronic components are dispersed into flexible printed circuit boards. These solutions are mechanically integrated but differ from each other in other ways. That is, the inactive electronic components that are metallically connected are different, and the sub-circuits are different.
This technique has been used successfully for robotic skins and has developed contact skins for a variety of robots, including the iCub humanoid robot, developed at the IIT Institute in Italy. The semi-rigid skin developed by this company is one of the most effective methods to cover most of the curvature of the body (arms of the iCub humanoid robot). It currently meets the most pressing needs of robotics, but sooner or later, an even higher output is needed.
Conceptual development and future trends related to skin
One of the most interesting developments in this technology is the electronic skin, which uses thin semiconductor transistors based on organic semiconductors, developed by the University of Tokyo and the University of Stanford. Organic semiconductors have an inherent bending ability due to their specific molecular structures, which in some way, help solve the problem of softness. The disadvantage here is that the transistors and sensors slow down when used with this material due to the low charge carrier mobility. In this material, electrons take longer to move than others. They are also less stable.
To make effective use of electronic technology in robotics or elsewhere, sensor data must be retrieved and transmitted in less than a millisecond (ms) so that the robot can react quickly. This means that single-crystal silicon, a high mobility material, would be a more viable option. The researcher’s team at the University of Glasgow is developing an electronic skin that can be processed using silicone and other superconducting materials using micro/nanofabrication tools.
But this again leads to a problem with flexibility because of the silicone cracks during bending. They have overcome the challenges by using an exchange print approach. There, silicon nanowires are mass-engraved from the wafer and printed on flexible plastic substrates. Then the skin is a rubber polymer called a polyamide with a small silicon nanowire on it that leads to thin-film transistors and sensors.
This concept is especially important for advancing prosthetics (the science of artificially creating and fitting body parts). This is because artificial limbs can be improved, but they are inherently tough. However, this “electronic skin” will be able to improve the way the prostate responds to touch.
With the development of artificial skin by the University of Glasgow, future prostate organs (artificial limbs) will be able to sense light and touch, as well as send signals to the brain and successfully respond to signals from the brain.
Once these barriers are overcome, the experience of using electronic skin can be further enhanced by using smaller and more efficient batteries and a body-friendly substance that is more closely related to real skin. It’s going to be interesting.
