The very fast evolution in wearable electronics drives the need for energy storage micro-devices, which have to be flexible. Micro-supercapacitors are of high interest because of their high power density, long cycle lifetime and fast charge and discharge. Recent developments on micro-supercapacitors focus on improving the energy density, overall electrochemical performance, and mechanical properties. In this review, the different types of micro-supercapacitors and configurations are briefly introduced. Then, the advances in carbon electrode materials are presented, including activated carbon, carbon nanotubes, graphene, onion-like carbon, and carbide-derived carbon. The different types of electrolytes used in studies on micro-supercapacitors are also treated, including aqueous, organic, ionic liquid, solid-state, and quasi-solid-state electrolytes. Furthermore, the latest developments in fabrication techniques for micro-supercapacitors, such as different deposition, coating, etching, and printing technologies, are discussed in this review on carbon electrode-based micro-supercapacitors.

Triboelectric nanogenerators (TENGs) that utilize triboelectrification and electrostatic induction to convert mechanical energy to electricity have attracted increasing interest in the last 10 years. As a universal physical phenomenon, triboelectrification can occur between any two surfaces that experience physical contact and separation regardless of the type of material. For this reason, many materials, including both organic and inorganic materials, have been studied in TENGs with different purposes. Although organic polymers are mainly used as triboelectric materials in TENGs, the application of inorganic nanomaterials has also been intensively studied because of their unique dielectric, electric, piezoelectric, and optical properties, which can improve the performance of TENGs. A review of how inorganic nanomaterials are used in TENGs would help researchers gain an overview of the progress in this area. Here, we present a review to summarize how inorganic nanomaterials are utilized in TENGs based on the roles, types, and characteristics of the nanomaterials.

Summary The sphere of activity between the wildlife and human has been more overlapped with the enlarged infrastructure. With using the energy harvesting‐storage technology, the warning signal can be easily generated and transmitted to the wildlife by a light stimulation. Here, the hybrid energy harvester with a triboelectric nanogenerator and a plate‐typed thermoelectric generator is integrated with a gold nanoflower‐based supercapacitor for directly storing energy. 23.7 V of the VOC and 0.86 μA of the ISC are generated through the triboelectric nanogenerator. For the thermoelectric generator, 40 mV and 10 mA of each electrical output are generated with the temperature difference of 6°C. The hybrid generator is optimized by changing the connection and adding components for the highest charging speed. The electrochemical characteristics of the supercapacitor are demonstrated with the cyclic voltammetry and discharging time in the galvanostatic charge‐discharge test. After storing the generated energy into the fabricated supercapacitor, an external photo‐sensing system is stimulated by an LED light operated by the stored electrical energy. By harvesting energy from the wildlife, the ability for providing an optical warning signal to the animals can be successfully demonstrated and open up a new field of ecologically friendly technology.
