Low-cost control and measurement circuit for the implementation of single element heat dissipation soil water matric potential sensor based on a SnSe2 thermosensitive resistor
(2021-02-02)
A low-cost signal processing circuit developed to measure and drive a heat dissipation soil matric potential sensor based on a single thermosensitive resistor is demonstrated. The SnSe2 has a high thermal coefficient, from ...
Synthesis of multiport resistors with piecewise-linear characteristics: a mixed-signal architecture
(John Wiley & Sons Ltd, 2005-07)
Non‐linear multiport resistors are the main ingredients in the synthesis of non‐linear circuits. Recently, a particular PWL representation has been proposed as a generic design platform (IEEE Trans. Circuits Syst.‐I 2002; ...
Versatile and easy-to-assemble measurement system for impedance-based structural health monitoring
(2011-12-01)
In this paper we present a versatile and easy-to-assemble measurement system for structural health monitoring (SHM) based on the electromechanical impedance (EMI) technique. The hardware of the proposed system consists ...
Mechanism of charge transport in castor oil-based polyurethane/carbon black composite (PU/CB)
(Elsevier B.V., 2012-01-15)
In order to identify and quantify the conduction mechanisms involved in the transport process, castor oil based polyurethane/carbon black composite (PU/CB) was introduced in a statistical model that reproduced the ac ...
