Self-powering amperometric sensor and biosensor

Journal of Electroanalytical Chemistry, 2012
Abstract 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, 2012
Abstract 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.

Study on the Self-Powered Electromagnetic Sensor

Applied Mechanics and Materials, 2013
For 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 optical sensor systems

TRANSDUCERS 2009 - 2009 International Solid-State Sensors, Actuators and Microsystems Conference, 2009
A 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.
