biodegradable triboelectric nanogenerator as a life time designed implantable Power Source
Science Advances, 2016Co-Authors: Qiang Zheng, Yang Zou, Yalan Zhang, Zhuo Liu, Bojing Shi, Xinxin Wang, Yiming Jin, Han Ouyang, Zhong Lin WangAbstract:Transient electronics built with degradable organic and inorganic materials is an emerging area and has shown great potential for in vivo sensors and therapeutic devices. However, most of these devices require external Power Sources to function, which may limit their applications for in vivo cases. We report a biodegradable triboelectric nanogenerator (BD-TENG) for in vivo biomechanical energy harvesting, which can be degraded and resorbed in an animal body after completing its work cycle without any adverse long-term effects. Tunable electrical output capabilities and degradation features were achieved by fabricated BD-TENG using different materials. When applying BD-TENG to Power two complementary micrograting electrodes, a DC-pulsed electrical field was generated, and the nerve cell growth was successfully orientated, showing its feasibility for neuron-repairing process. Our work demonstrates the potential of BD-TENG as a Power Source for transient medical devices.

a paper based nanogenerator as a Power Source and active sensor
Energy and Environmental Science, 2013Co-Authors: Qize Zhong, Zhong Lin Wang, Junwen Zhong, Jun ZhouAbstract:Paper-based functional electronic devices endow a new era of applications in radio-frequency identification (RFID), sensors, transistors and microelectromechanical systems (MEMS). As an important component for building an all paper-based system that can work independently and sustainably, a paper-based Power Source is indispensable. In this study, we demonstrated a paper-based nanogenerator (pNG) that can convert tiny-scale mechanical energy into electricity. The pNG relies on an electrostatic effect, and the electrostatic charges on the paper were generated by the corona method. The instantaneous output Power density of a single-layered pNG reached ∼90.6 μW cm−2 at a voltage of 110 V, and this instantaneously illuminated 70 LEDs. In addition, by sticking the pNG to a movable object, such as the page of a book, the Power harvested from the mechanical action of turning the page can drive an LED, which presents its outstanding potential in building paper-based, self-Powered systems and as active sensors.

Harmonic-resonator-based triboelectric nanogenerator as a sustainable Power Source and a self-Powered active vibration sensor
Advanced Materials, 2013Co-Authors: J. Chen, Te Chien Hou, Weiqing Yang, Ya Yang, Qingshen Jing, Peng Bai, Guang Zhu, Zhong Lin WangAbstract:A harmonic-resonator-based triboelectric nanogenerator (TENG) is presented as a sustainable Power Source and an active vibration sensor. It can effectively respond to vibration frequencies ranging from 2 to 200 Hz with a considerably wide working bandwidth of 13.4 Hz. This work not only presents a new principle in the field of vibration energy harvesting but also greatly expands the applicability of TENGs.

An electric-eel-inspired soft Power Source from stacked hydrogels
Nature, 2017Co-Authors: Thomas B. H. Schroeder, Anirvan Guha, Aaron Lamoureux, Gloria Vanrenterghem, David Sept, Max Shtein, Jerry Yang, Michael MayerAbstract:Miniature hydrogel compartments in scalable stacked and folded geometries were used to prepare a contact-activated artificial electric organ. The electric eel can generate electrical discharges of 100 watts to stun prey, but should you X-ray an eel, you wouldn't find a battery pack inside. Instead, thousands of cells called electrocytes are arranged along its body, each producing a small ion gradient and therefore a potential difference across them. Now, Michael Mayer and colleagues have developed a hydrogel-based system that mimics the electrocyte mechanism and could be used as a soft Power Source for robotics. They arrange sets of ion-selective hydrogels in series to generate ion gradients across a group of four hydrogel droplets. These droplets can either be arranged in series in a microfluidic set-up, or be stacked in parallel by folding up an array of hydrogels using origami principles. The net result is a Power Source that is able to generate voltages similar to those generated by the electric eel. Progress towards the integration of technology into living organisms requires electrical Power Sources that are biocompatible, mechanically flexible, and able to harness the chemical energy available inside biological systems. Conventional batteries were not designed with these criteria in mind. The electric organ of the knifefish Electrophorus electricus (commonly known as the electric eel) is, however, an example of an electrical Power Source that operates within biological constraints while featuring Power characteristics that include peak potential differences of 600 volts and currents of 1 ampere^ 1 , 2 . Here we introduce an electric-eel-inspired Power concept that uses gradients of ions between miniature polyacrylamide hydrogel compartments bounded by a repeating sequence of cation- and anion-selective hydrogel membranes. The system uses a scalable stacking or folding geometry that generates 110 volts at open circuit or 27 milliwatts per square metre per gel cell upon simultaneous, self-registered mechanical contact activation of thousands of gel compartments in series while circumventing Power dissipation before contact. Unlike typical batteries, these systems are soft, flexible, transparent, and potentially biocompatible. These characteristics suggest that artificial electric organs could be used to Power next-generation implant materials such as pacemakers, implantable sensors, or prosthetic devices in hybrids of living and non-living systems^ 3 , 4 , 5 , 6 .

Power balance of a hybrid Power Source in a Power plant for a small propulsion aircraft
IEEE Transactions on Power Electronics, 2009Co-Authors: Elena Bataller-Planes, Fortunato Ortí, Miroslav Vasi?, Santa Concepcion Huerta, Matías Trocki, Jonay Mosquera, Nieves Lapeña-Rey, Pablo Zumel, Yagoyago Torroja, Javier Portilla, Jesus A. Oliver, Miroslav Vasic, Óscar García, Félix Moreno, Jose A. CobosAbstract:This paper analyzes two different architectures for a hybrid Power Source comprising a polymer electrolyte membrane fuel cell and a Li ion battery. The hybrid Power Source feeds the propulsion motor of an all-electrical aircraft, the Boeing Fuel Cell Demonstrator. Unregulated and regulated hybrid Power architectures are examined. The regulation is achieved by means of a controllable series boost converter (SBC) connected in series with the fuel cell. Both architectures have been simulated, implemented, and tested in the Boeing Fuel Cell Demonstrator airplane.
