Design and Development of NiTi Shape Memory Alloy Belt for Waste Heat Energy Recovery System

Simulation Analysis and Experimental Study of Piezoelectric Power Generation Device Based on Shape Memory Alloy Drive

“…The emission form is complicated and cannot be effectively utilized on a large scale, which not only wastes a lot of energy but also pollutes the environment, but also does not conform to the current social development requirements of low carbon and environmental protection, energy saving, and consumption reduction, and needs to be changed urgently. At present, people's research on intelligent materials has been more in-depth, with piezoelectric [ 1 – 4 ], electrostatic [ 5 , 6 ], electromagnetic [ 7 – 9 ], shape memory alloy [ 10 , 11 ], and other intelligent materials based on the absorption of waste heat, and power generation research is widely carried out, forming a variety of secondary energy reuse technology and methods, showing a great situation of vigorous development.…”

“…At present, the main thermal power generation technologies are temperature difference power generation [ 12 – 14 ], pyroelectric power generation [ 15 – 17 ], thermomagnetic power generation [ 18 , 19 ], and thermoelastic power generation [ 11 , 20 ], but they all will be restricted by some conditions and not suitable for wide application in waste heat power generation systems. The former can convert thermal energy into stress-strain and has a strong thermal-mechanical energy conversion capability, while the latter can convert stress-strain into electrical energy and has been applied to wireless networks, MEMS devices, and self-powering of portable equipment.…”
