Si is a promising material for applications as a high-capacity anode material of lithium-ion batteries. However, volume expansion, poor electrical conductivity, and a short cycle life during the charging/discharging process limit the commercial use. In this paper, new ternary composites of sea urchin-like Si@MnO2@reduced graphene oxide (rGO) prepared by a simple, low-cost chemical method are presented. These can effectively reduce the volume change of Si, extend the cycle life, and increase the lithium-ion battery capacity due to the dual protection of MnO2 and rGO. The sea urchin-like Si@MnO2@rGO anode shows a discharge specific capacity of 1282.72 mAh g−1 under a test current of 1 A g−1 after 1000 cycles and excellent chemical performance at different current densities. Moreover, the volume expansion of sea urchin-like Si@MnO2@rGO anode material is ~50% after 150 cycles, which is much less than the volume expansion of Si (300%). This anode material is economical and environmentally friendly and this work made efforts to develop efficient methods to store clean energy and achieve carbon neutrality.

“…Electrical stimulation therapy has been regarded as a safe and convenient method for the treatment of several diseases in recent years, especially in the field of regenerative medicine and neurology such as wound healing, neuroplasticity, and neuro repairing. [ 23 , 59 , 60 , 61 ] For wound healing, the concept came from the endogenous electric fields, which can guide fibroblasts to migrate to the wound area. [ 62 , 63 , 64 , 65 ] Specifically, it has been reported that cell proliferation and migration can be efficiently enhanced by electric fields, providing the benefits for wound healing.…”

Single crystal metal-free halide perovskites have received great attention in recent years owing to their excellent piezoelectric and ferroelectric properties. However, the nanotoxicity and piezoelectricity within the nanoscale of such materials have yet been reported for the demonstration of practical applications. In this work, the observation of intrinsic piezoelectricity in metal-free perovskite (MDABCO-NH 4 I 3 ) films using piezoresponse force microscopy (PFM) is reported. A cytotoxicity test is also performed on MDABCO-NH 4 I 3 to evaluate its low-toxic nature. The as-synthesized MDABCO-NH 4 I 3 is further integrated into a piezoelectric nanogenerator (PENG). The MDABCO-NH 4 I 3 -based PENG (MN-PENG) exhibits optimal output voltage and current of 15.9 V and 54.5 nA, respectively. In addition, the MN-PENG can serve as a self-powered strain sensor for human-machine interface applications or be adopted in in vitro electrical stimulation devices. This work demonstrates a path of perovskite-based PENG with high performance, low toxicity, and multifunctionality for future advanced wearable sensors and portable therapeutic systems.

“…Fortunately, self‐powered devices provide an alternative strategy to this issue. [ 10–12 ] At present, several types of electromechanical conversion principles, including capacitance, [ 13,14 ] piezoresistance, [ 15 ] piezoelectricity, [ 16 ] and triboelectricity, [ 17–19 ] are often employed to provide the electrical signal for e‐skins. Particularly, as an emerging technology for energy harvesting and self‐powered sensing, triboelectric nanogenerator (TENG) has the advantages of simple structure, easy to fabricate, and diverse material options, which enables to convert of ubiquitous mechanical energy into an electrical signal.…”

The simultaneous achievement of multiple functional attributes, such as flexibility, stretchability, transparency, comfortability, biodegradability, and self-powered ability into electronic skins (e-skins) is vital to their long-term practical applications. Due to the internal contradiction between functional material combination and simple structural design, this kind of multifunctional e-skin has rarely been fabricated or even reported. To this end, chitosan (CS), a natural material with remarkable biocompatibility, biodegradability, and electron-donating ability, is integrated with a single-mode triboelectric nanogenerator (TENG) to develop a multifunctional e-skin, which includes sweat permeability, controllable biodegradability, high transparency, and selfpowered sensing ability. In addition, a facile, efficient, and large-scale fabrication strategy is proposed to construct stretchable, ultrathin, transparent, and shape-adaptable gold nanofibers (Au NFs) electrodes. Furthermore, the e-skin can achieve a voltage response pressure sensitivity of 0.012 kPa −1 in the pressure range of 0-70 kPa and a fast response time of 70 ms. Finally, it shows controllable and excellent degradability in various solutions. It is believed that the proposed e-skin based on the design and integration of CS and Au NFs will provide a paradigm shift for the next-generation self-powered transient electronics.
