Using an Al-foil of thickness ≈ 18 μ m as a substrate and electrode, a piezoelectric nanogenerator (NG) that is super-fl exible in responding to the wavy motion of a very light wind is fabricated using ZnO nanowire arrays. The NG is used to harvest the energy from a waving fl ag, demonstrating its high fl exibility and excellent conformability to be integrated into fabric. The NG is applied to ...

Well-aligned ZnO nanostructures have been intensively studied over the last decade for remarkable physical properties and enormous applications. Here, we describe a one-step fabrication technique to synthesis freestanding ZnO nanorod/graphene/ZnO nanorod double heterostructure. The preparation of the double heterostructure is performed by using thermal chemical vapor deposition (CVD) and prehea...

Harvesting energy from multiple sources available in our personal and daily environments is highly desirable, not only for powering personal electronics, but also for future implantable sensor-transmitter devices for biomedical and healthcare applications. Here we present a hybrid energy scavenging device for potential in vivo applications. The hybrid device consists of a piezoelectric poly(vin...

Harvesting energy from irregular/random mechanical actions in variable and uncontrollable environments is an effective approach for powering wireless mobile electronics to meet a wide range of applications in our daily life. Piezoelectric nanowires are robust and can be stimulated by tiny physical motions/disturbances over a range of frequencies. Here, we demonstrate the first chemical epitaxia...

This paper presents a cascade-type compact hybrid energy cell (CHEC) that is capable of individually and concurrently harvesting solar and strain energies. The cell is made up of an n-p homojunction nanowire (NW)-based piezoelectric nanogenerator and a nanocrystalline/amorphous-Si:H single junction cell. Under optical illumination of 10 mW/cm and mechanical vibration of 3 m/s at 3 Hz frequency,...

A living species has numerous sources of mechanical energy, such as muscle stretching, arm/leg swings, walking/running, heart beats, and blood flow. We demonstrate a piezoelectric nanowire based nanogenerator that converts biomechanical energy, such as the movement of a human finger and the body motion of a live hamster (Campbell's dwarf), into electricity. A single wire generator (SWG) consist...
