Self-sustained autonomous wireless sensing based on a hybridized TENG and PEG vibration mechanism

“…At the same time, biomechanical energy sources usually include various types of human motions, and an EH with a single mechanism may not be able to fully utilize all of the mechanical energy generated by such movements ( Liu et al., 2020a ; Zhang et al., 2019b ). Therefore, hybridized wearable EHs with the combination of multiple energy conversion mechanisms, including TENG, PENG, and EMG, have been put forward for harvesting mechanical energy, which can leverage the advantages of each mechanism's characteristics and as a complementary part for each other ( Tang et al., 2021 ; Wang et al., 2021 ; Zhu et al., 2021 ). For non-flexible wearable EHs, EMG is generally integrated for its high output current compared with PENG and TENG ( Toyabur Rahman et al., 2020 ; Zhang et al., 2019c ).…”

Summary Body sensor network (bodyNET) offers possibilities for future disease diagnosis, preventive health care, rehabilitation, and treatment. However, the eventual realization demands reliable and sustainable power sources. The flourishing energy harvesters (EHs) have provided prominent techniques for practically addressing the concurrent energy issue. Targeting for a specific energy source, wearable EHs with a sole conversion mechanism are well investigated. Hybrid EHs integrating different effects for a single source or multi-sources are attaining growing attention, for they provide another degree of freedom concerning a higher-level energy utility. Merging EHs with other functional electronics, diversified functional self-sustainable systems are developed, paving the way for the accomplishment of bodyNET. This review introduces the evolution of wearable EHs from a single effect to hybridized mechanisms for multiple energy sources and wearable to implantable self-sustainable systems. Last, we provide our perspectives on the future development of hybrid EHs to be more competitive with conventional batteries.

“…However, current sustainable HMIs enabled by the integrated energy harvesting units are not suitable for continuous wireless monitoring or fast information exchange due to the inevitable charging phase [61,[324][325][326]. The additional energy harvesters or power management circuits also increase the size and cost of the whole device, reducing the applicability for wearable scenarios.…”

Entering the 5G and internet of things (IoT) era, human–machine interfaces (HMIs) capable of providing humans with more intuitive interaction with the digitalized world have experienced a flourishing development in the past few years. Although the advanced sensing techniques based on complementary metal-oxide-semiconductor (CMOS) or microelectromechanical system (MEMS) solutions, e.g., camera, microphone, inertial measurement unit (IMU), etc., and flexible solutions, e.g., stretchable conductor, optical fiber, etc., have been widely utilized as sensing components for wearable/non-wearable HMIs development, the relatively high-power consumption of these sensors remains a concern, especially for wearable/portable scenarios. Recent progress on triboelectric nanogenerator (TENG) self-powered sensors provides a new possibility for realizing low-power/self-sustainable HMIs by directly converting biomechanical energies into valuable sensory information. Leveraging the advantages of wide material choices and diversified structural design, TENGs have been successfully developed into various forms of HMIs, including glove, glasses, touchpad, exoskeleton, electronic skin, etc., for sundry applications, e.g., collaborative operation, personal healthcare, robot perception, smart home, etc. With the evolving artificial intelligence (AI) and haptic feedback technologies, more advanced HMIs could be realized towards intelligent and immersive human–machine interactions. Hence, in this review, we systematically introduce the current TENG HMIs in the aspects of different application scenarios, i.e., wearable, robot-related and smart home, and prospective future development enabled by the AI/haptic-feedback technology. Discussion on implementing self-sustainable/zero-power/passive HMIs in this 5G/IoT era and our perspectives are also provided.
