“…The nanogenerators with a single hemisphere layer generated an output voltage of up to 4 V at a current density of 0.13 µA cm −2 (Figure 15d), which were increased up to 6 V and 0.2 µA cm −2 by stacking three layers of such hemispheres layer-by-layer. [126] As discussed above, one-dimensional nanostructures (such as metallic nanowires) could sustain much higher tensile strain (≈10%) before failure over their bulky counterparts (<1%). Simi larly, one-dimensional polymer-based piezoelectric materials have been used as effective building blocks for fabrication of stretchable piezoelectric devices.…”

“…Highly ordered piezoelectric hemispheres could be embedded into PDMS matrices, leading to stretchable energy harvesters, [126] as illustrated in Figure 15c. Polystyrene (PS) beads were deposited on SiO 2 /Si substrate to form the array as the templates, which was followed by sputtering of 100-nm-thick ZnO or PZT film on top of PS beads.…”

The development of ultra‐compliant power sources is crucial for their seamless integration with next‐generation skin‐like wearable and implantable biomedical systems for long‐term health monitoring. Toward this goal, stretchable energy storage and conversion devices (ESCDs), including supercapacitors, lithium‐ion batteries (LIBs), solar cells, and generators are now attracting intensive worldwide research efforts. The purpose of this review is to discuss the latest achievements in the development of such stretchable energy devices in the context of biomedical applications. We first review the viable strategies and methodologies of fabricating stretchable energy storage and conversion devices. Then, we focus on description of various types of soft energy devices from a materials point of view. Furthermore, we discuss the challenges and opportunities in the design of truly conformal soft energy systems, including various key parameters, such as energy density, stability, and scalability.

Abstract:Energy harvesting is the most effective way to respond to the energy shortage and to produce sustainable power sources from the surrounding environment. The energy harvesting technology enables scavenging electrical energy from wasted energy sources, which always exist everywhere, such as in heat, fluids, vibrations, etc. In particular, piezoelectric energy harvesting, which uses a direct energy conversion from vibrations and mechanical deformation to the electrical energy, is a promising technique to supply power sources in unattended electronic devices, wireless sensor nodes, micro-electronic devices, etc., since it has higher energy conversion efficiency and a simple structure. Up to now, various technologies, such as advanced materials, micro-and macro-mechanics, and electric circuit design, have been investigated and emerged to improve performance and conversion efficiency of the piezoelectric energy harvesters. In this paper, we focus on recent progress of piezoelectric energy harvesting technologies based on PbZr x Ti 1´x O 3 (PZT) materials, which have the most outstanding piezoelectric properties. The advanced piezoelectric energy harvesting technologies included materials, fabrications, unique designs, and properties are introduced to understand current technical levels and suggest the future directions of piezoelectric energy harvesting.

We have successfully synthesized highly dense and well aligned zinc oxide (ZnO) nanowires ( The results showed that upon bending, an anisotropic voltage polarity is generated on the two sides. Indicating that, this double sided NG can be used as a self-powered voltage polarity based direction sensor. The results of the present flexible double sided NG is very promising for harvesting energy from irregular mechanical energy sources in the surrounding environment. In addition, the fabricated configuration showed stability for sensing and can be used in surveillance and security applications.
