Porous Piezoelectric Fibers
In article number 2105811, Miso Kim and co‐workers establish a distinctive design approach to enhance piezoelectric performance via structural morphology tailoring in piezoelectric polymer fibers. Providing water molecules under ambient humidity conditions during electrospinning is the most crucial consideration in this study.
Electrospun polymeric piezoelectric fibers have a considerable potential for shape‐adaptive mechanical energy harvesting and self‐powered sensing in biomedical, wearable, and industrial applications. However, their unsatisfactory piezoelectric performance remains an issue to be overcome. While strategies for increasing the crystallinity of electroactive β phases have thus far been the major focus...
In article number 1903519, Sang‐Woo Kim, Jung Ho Kim, and co‐workers present two‐dimensional (2D) material based piezoelectric and triboelectric nanogenerators that can be used as a power source for devices that can be patchable and implantable by converting mechanical energy generated inside and outside the human body into electrical energy.
With the development of technology, electronic devices are becoming more miniaturized and multifunctional. With the development of small electronic devices, they are changing from the conventional accessory type, which is portable, to the patchable type, which can be attached to a person's apparel or body, and the eatable/implantable type, which can be directly implanted into the human body. In this...
Pyroelectric energy harvesting systems have recently received substantial attention for their potential applications as power generators. In particular, the pyroelectric effect, which converts thermal energy into electrical energy, has been utilized as an infrared (IR) sensor, but upcoming sensor technology that requires a miniscule amount of power is able to utilize pyroelectric nanogenerators (PyNGs)...
