An interest with movie technology that demonstrated robots perform self-repair through a liquid formula propelled a Purdue University professor to make his own revelations – which are presently driving the path for advancements in self-controlling gadgets, for example, purchaser electronics and defense innovations.
The Purdue group, driven by Wenzhuo Wu, the Ravi and Eleanor Talwar Rising Star Assistant Professor of Industrial Engineering, has made wearable innovation to change over mechanical energy into electrical energy.
“Our work presents an important step toward the practical realization of self-powered, human-integrated technologies,” Wu said.
The Purdue group developed a liquid-metal-inclusion based triboelectric nanogenerator, called LMI-TENG. Triboelectric energy reaping transducers – gadgets which help preserve mechanical energy and transform it into power – are anticipated to be a $480 million market by 2028, as indicated by IDTechEx.
The LMI-TENG can collect and detect the biomechanical signals from the body and utilize those to help control and direct technological gadgets. The LMI-TENG comprises of a layer of liquid metal embedded functional silicone sandwiched between two Ecoflex layers.
The Purdue technology is highlighted in the February edition of the Journal of Materials Chemistry A, which named it one of 2019’s HOT papers.
“We realized that liquid represents the ultimate form of anything that can be deformable and morphing into different shapes,” Wu said. “Our technology will enable wearable electronics to take otherwise wasted energy and transform it into energy that can power and control electronic devices and tools used in military defense and consumer applications. Our technology allows the synergistic engineering of TENG components at the material, structural and output levels.”
Wu said the Purdue technology has applications for many self-powered innovations for emerging technologies, such as wearable sensors, pervasive computing, advanced health care, human-machine interfaces, robotics, user interfaces, augmented reality, virtual reality, teleoperation and the Internet of Things.
Their work lines up with Purdue’s Giant Leaps celebration, acknowledging the university’s global advancements in artificial intelligence and health as a major aspect of Purdue’s 150th anniversary. AI and health are two of the four themes of the yearlong festival’s Ideas Festival, intended to feature Purdue as an intellectual center solving real-world issues.
Scientists worked with the Purdue Research Foundation Office of Technology Commercialization to patent the innovation, and they are searching for accomplices to keep creating it.
