3D Smart Energy Devices: The Future of Eco-Friendly Heating and Cooling
In the quest for sustainable energy solutions, a groundbreaking innovation has emerged. Researchers from DGIST have developed a remarkable "3D Smart Energy Device" that offers dual-function reversible heating and cooling capabilities, addressing environmental concerns and potential energy savings.
A Breakthrough in Energy Efficiency
The "3D Smart Energy Device" was created by a team led by Professor Bonghoon Kim from the Department of Robotics and Mechatronics Engineering at DGIST. This device stands out due to its ability to heat and cool simultaneously, a significant advancement in the field of solar absorption and radiative cooling.
The Dual-Function Mechanism
At the heart of this innovative device lies a unique mechanism. When the 3D structure is mechanically peeled open, a lower layer of silicone elastomer and silver is exposed, facilitating radiative cooling. Conversely, when the structure is closed, the surface painted black absorbs solar heat to produce heating. This versatility revolutionizes the efficiency and adaptability of heating and cooling devices, the perfect eco-friendly solutions for both macro and micro-scale applications.
Overcoming the Challenges of Traditional Methods
The challenge in traditional heating and cooling methods has always been their one-directional functionality and lack of scalability. Prof. Kim’s team has addressed these limitations with their "3D Smart Energy Device." By allowing for dynamic control over heat generation and dissipation, this technology can significantly reduce energy consumption in both buildings and electronic devices.
Broad Applicability
Tests conducted on a variety of substrates, including skin, glass, steel, aluminum, copper, and polyimide, have confirmed the device’s broad applicability. The ability to modulate thermal properties by adjusting the angle of the 3D structure further enhances its practicality.
Authoritative Publication and Support
The research was published in the prestigious journal "Advanced Materials" and was supported by the "Global Bioconvergence Interfacing Leading Research Center (ERC)" and the "Nano and Materials Technology Development Project" of the National Research Foundation of Korea.
