Self-powering amperometric sensor and biosensor
Journal of Electroanalytical Chemistry, 2012Abstract A unique Prussian blue nanotubes sensor using a two-compartment cell derives the current signal from the chemical energy of the hydrogen peroxide analyte, without input of electrical potentials, is described. The Prussian blue reduces hydrogen peroxide and is itself reduced by electron flow from the counter reaction at the auxiliary ...

Nanogenerator as self-powered vibration sensor
Nano Energy, 2012Abstract Vibration is one of the most popular phenomena that exists in our daily life. Detection of mechanical vibration usually uses laser technology. Here, we demonstrated the first application of a piezoelectric nanogenerator (NG) as a self-powered sensor for detecting the vibration status of a cantilever.

A self-powered damage detection sensor
The Journal of Strain Analysis for Engineering Design, 2003All existing methods of embedded damage-detecting sensors require an external power source and a means of transmitting the data to a central processor. This paper presents a novel self-powered strain sensor capable of transmitting data wirelessly to a remote receiver.

Study on the Self-Powered Electromagnetic Sensor
Applied Mechanics and Materials, 2013For the situation that external power supply can not be used in some special occasions , the internal factors of them should be adopted to achieve the self-powered. Inspired by the phenomenon that some passive electromagnetic induction sensors produce electronic pulses signal, the design proposes an electronic devices that can obtain power without ...

Self Powered Fiber Optical Sensors
SPIE Proceedings, 1989The problem of supplying power to optical and in particular fiber-optical sensors may be solved by generating electrical energy locally. This idea is illustrated here with several optical sensors, taken primarily from mechanical measurement applications.

Self-powered optical sensor systems
TRANSDUCERS 2009 - 2009 International Solid-State Sensors, Actuators and Microsystems Conference, 2009A 0.35 µm CMOS process has been used for on-chip integration of a sun sensor composed of a 2×2 photodiode array and a current-to-voltage amplifier. Unlike conventional sun sensors, a shade profile proportional to the angle of incidence of incoming light is projected onto the photodiodes.

Toward self-powered sensor networks
Nano Today, 2010Summary The future of nanotechnology is likely to focus on the areas of integrating individual nanodevices into a nanosystem that acts like living specie with sensing, communicating, controlling and responding. A nanosystem requires a nano-power source to make the entire package extremely small and high performance.
