Design and implementation of a low cost particulate material transducer
(Institute of Electrical and Electronics Engineers Inc., 2018)
This work presents the design, implementation, calibration and test of a transducer system for Particle Material - PM based on the sensor GP2Y1010. This sensor is the principal element of many commercial PM transducers, ...
Low cost robot design for research and educational purposes
(Universidade Federal do Mato Grosso (UFMT) - Campus de Rondonópolis, 2020)
Design and development of a low-cost prosthesis directed to the activity with a gasoline brush cutter: A case study
(2017-01-01)
In Brazil, the rate of people with disabilities resulting from amputation is relevant. The distribution of high-tech prostheses only meets a small portion of the population. On the other hand it is known that most of the ...

Analysis of the electrical and optical properties of PEDOT:PSS/PVA blends for low-cost and high-performance organic electronic and optoelectronic devices
(Iop Publishing Ltd, 2015-03-01)
In this study we propose the use of a blend, comprising poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) and polyvinyl alcohol (PVA), to be used as flexible, semitransparent and highly conductive material ...
Low-cost piezoelectric transducer for ceramic grinding monitoring
(2019-09-01)
This paper presents a performance assessment of the low-cost thin-disk piezoelectric diaphragm (PZT) for the surface integrity monitoring in the grinding operation. PZT diaphragms are flexible, low-cost, and smart devices, ...
Didactic demonstration of the interaction between electric currents
(Soc Brasileira Fisica, 2007-10-01)
We present the first crucial experiment by Ampere that shows the interaction of two metallic wires carrying steady currents. We discuss its importance in the history of physics. We also present a modern reproduction of the ...
A composite of polyethylene terephthalate and sugarcane ash-coated FeSO4 center dot 7H(2)O (PETSCA/Fe) as a low-cost adsorbent material
(Elsevier B.V., 2017-02-01)
A new type of composite adsorbent material matrix was prepared containing polyethylene terephthalate and sugarcane ash-coated FeSO4 center dot 7H(2)O particles (PETSCA/Fe). The dependence of the adsorption properties of ...
