“…Taking the studies mentioned above as examples [ 143 , 144 ], they can bring microwatt levels of power reduction, while the power consumption of portable sensors is often at the milliwatt level. Alternatively, enhancing the power supply can solve the energy problem including using batteries with a high energy density [ 145 ] and fast charging capability [ 146 , 147 ], as well as applying self-powered designs that sensors obtain energy from the behavior of wearer [ 148 , 149 ], body temperature [ 150 , 151 ], body fluids [ 152 ], friction[ 153 ], raindrop [ 154 ], and sunlight [ 155 ]. In addition to using high-performance batteries, power management strategies provide support to improve the battery life of compact wearable sensors further [ 156 ].…”

Wearable sensors have demonstrated wide applications from medical treatment, health monitoring to real-time tracking, human-machine interface, smart home, and motion capture because of the capability of in situ and online monitoring. Data acquisition is extremely important for wearable sensors, including modules of probes, signal conditioning, and analog-to-digital conversion. However, signal conditioning, analog-to-digital conversion, and data transmission have received less attention than probes, especially flexible sensing materials, in research on wearable sensors. Here, as a supplement, this paper systematically reviews the recent progress of characteristics, applications, and optimizations of transistor amplifiers and typical filters in signal conditioning, and mainstream analog-to-digital conversion strategies. Moreover, possible research directions on the data acquisition of wearable sensors are discussed at the end of the paper.

“…Different types of energy transducing mechanisms and energy harvesters have been developed to scavenge the dissipated energy. [22][23][24][25] Moreover, the energy supply units should possess the characteristics of portability, sustainability, miniaturization, wearability, or even implantability. [26][27][28] The triboelectrification effect (TE), as one of the major energy transducing mechanisms, was first utilized to construct triboelectric nanogenerators (TENGs) in 2012 by Prof. Wang and his team.…”

Ocean contain abundant clean energies including tidal and wave, but such energies are known for low frequency and large excitation amplitude, posing considerable challenges for high‐efficiency energy conversion. As an emerging technology, triboelectric nanogenerators (TENGs) have been widely used in energy harvesting and novel sensor design due to their high sensitivity and flexible structure. Meanwhile, they show great advantages in the low‐frequency environment (<5 Hz), and display great potential for deployment in remote ocean waters, and construction of large‐scale TENG networks. In this review, firstly, the working principle of TENGs and various configurations developed for the marine environment are introduced, which mainly include solid–solid and solid–liquid interfaces. Then, from the viewpoint of power improvement, authors are most concerned about the modification methods of materials such as surface modification, electron injection, and chemical doping. Meanwhile, improved technologies for energy harvesters in marine environment are discussed in detail, such as improving the hydrophobicity and degradation of materials, studying the self‐healing ability of materials, and designing power management circuits. Finally, the current challenges are summarized, and research trends are given from both short‐term and long‐term perspectives.
