“…Regarding the power supply to these two kinds of monitoring, the traditional method is to use batteries that cause electrochemical pollution or to connect to the grid via a complicated wired system. In the past 20 years, self-powered technologies with ambient energy harvesting systems have attracted tremendous attention as promising directions in transportation research filed because of their potential to achieve environmental protection, energy saving, and real-time monitoring of sensor nodes (Fu et al, 2021;Chen and Wang, 2017;Lewis et al, 2014). Ambient energy harvesting in the railway environment is the key technology to achieve the self-powering of monitoring systems (Gonza ´lez-Gil et al, 2013;Bosso et al, 2021).…”

Lower-limb motion monitoring is highly desired in various application scenarios ranging from rehabilitation to sports training. However, there still lacks a cost-effective, energy-saving, and computational complexity-reducing solution for this specific demand. Here, a motion capturing and energy harvesting hybridized lower-limb (MC-EH-HL) system with 3D printing is demonstrated. It enables low-frequency biomechanical energy harvesting with a sliding block-rail piezoelectric generator (S-PEG) and lower-limb motion sensing with a ratchet-based triboelectric nanogenerator (R-TENG). A unique S-PEG is proposed with particularly designed mechanical structures to convert lower-limb 3D motion into 1D linear sliding on the rail. On the one hand, high output power is achieved with the S-PEG working at a very low frequency, which realizes self-sustainable systems for wireless sensing under the Internet of Things framework. On the other hand, the R-TENG gives rise to digitalized triboelectric output, matching the rotation angles to the pulse numbers. Additional physical parameters can be estimated to enrich the sensory dimension. Accordingly, demonstrative rehabilitation, human-machine interfacing in virtual reality, and sports monitoring are presented. This developed hybridized system exhibits an economic and energy-efficient solution to support the need for lower-limb motion tracking in various scenarios, paving the way for self-sustainable multidimensional motion tracking systems in near future.

“…Since the past decade there has been a growing interest in energy harvesters using piezoelectric materials [1][2][3]. Several studies, for instance [4][5][6], have been conducted on piezoelectric energy harvesters. These studies tended to focus on various orientations for the generator including inward, outward, and tilted configurations.…”

This paper deals with a new design of a thermo-magnetically activated piezoelectric generator. This proposed generator exploits the temperature-dependent magnetization of a ferromagnetic material, which is exposed to temporary change of temperature cycles. To promote a better understanding of the operation of this mechanism, a global coupled numerical model is presented, which is able to predict the static and dynamic behavior of the generator. It is shown that with some modifications to the physical design, the generator can be tuned for different activation temperatures. Energy densities of 280 and 67 µJcm−3 were achieved by the proposed model of the generator for its opening and closing commutation, respectively.
