What not can be done in the labs? If the researchers are so proficient and curious to utilize each every pinch of their knowledge to make something that can ease the humans’ efforts or even change the human parts to make them work. Medical devices have drastically changed in terms of functioning, equipment, and accessories.
Researchers at the University of Glasgow created an artificial skin which is sensitive to touch. The best part of this skin is it is totally self-powered due to photovoltaic installation. This innovation will generate some new possibilities for the prosthetics, as the currently utilized parts utilize a large amount of energy that is majorly powered by external power sources. The new concept of developed by the research will not only solve the power issues in case of battery drain but it will also ease the design of the system and make it more portable.
The mechanism works on the basis of pressure sensors that reduces the consumption of the electricity and uses only 20 nanowatts of charge per square centimeter which is further generated from light. The graphene made pressure sensors has a layer of 2D carbon material above it which is kept transparent in with the intention that photovoltaic cell below can soak light from the environment.
The gentle touch of 0.11 kPa proves the precision of sensor’s sensitivity that helps the device to generate enough energy for its functioning.
Dr. Dahiya, from the University of Glasgow’s School of Engineering, stated that human skin is an extremely intricate structure competent of identifying force, temperature, and surface through a series of neurological sensors which transmit signals generated by skin to the brain.
Skin competent of touch understanding also unlocks the prospect of building robots that can make a better decision in terms of human safety. Considering a robot functioning on a construction after the introducing these prosthetics on a robot is much less likely to injure or harm a human co-worker if it identifies that an individually entered the area and can halt the operation by itself before the injury takes place.
The team also plans to develop some wearable systems in the future to clear the way towards affordable healthcare.
