This paper presents a robust control strategy for the autonomous operation of a microgrid consisting of electronically coupled distributed generation (DG) units. The DG units are connected to a point of common coupling, and supply a load, which can be unbalanced and/or nonlinear. In practice, the load is usually unknown in terms of network topology and(More)
This paper reports on the successful fabrication of a multilayered hybrid printed circuit board (PCB) for applications in the consumer electronics products, medical technologies, and military equipment. The PCB was fabricated by screen-printing silver (Ag) flake ink, as metallization layer, and UV acrylic-based ink, as dielectric layer, on different(More)
A fully printed piezoelectric based touch sensitive skin has been successfully fabricated using screen printing technique. The device, consisting of a 4×4 array of printed sensors and interconnect lines, was fabricated on a flexible polyethylene terephthalate (PET) substrate, using silver (Ag) ink. Screen printed polyvinylidene fluoride (PVDF), as a(More)
A novel paper based surface enhancemed Raman spectroscopy (SERS) substrate was fabricated by gravure printing single and double layers of silver nanoparticle (NP) ink, with a particle size of ~20-50 nm, as metallization layer on a paper from Mitsubishi (NB-RC3GR120). The capability of the SERS substrate for detection of toxic heavy metal compounds such as(More)
A novel flexible printed strain gauge was fabricated successfully on a flexible paper substrate using flexography printing process. Silver (Ag) ink was printed on the paper substrate as metallization layer. The performance of the printed device was investigated by subjecting the strain gauge to a 3-point bend test, with a displacement of 1 mm and 2 mm at 3(More)
A novel flexible fully printed capacitive based pressure sensor was designed and fabricated using screen printing technique. Silver (Ag) ink and polydimethylsiloxane (PDMS) were printed on a flexible polyethylene terephthalate (PET) substrate as metallization and dielectric layers, respectively. The capacitive response of the sensor demonstrated a(More)
Flexible dry electrode based on multi-walled carbon nanotube (MWCNT)/polydimethylsiloxane (PDMS) composite, for monitoring electrocardiogram (ECG) signals, has been developed. The dry ECG electrode was fabricated by screen printing silver (Ag) ink on flexible polyethylene terephthalate (PET) substrate, followed by bar coating of MWCNT/PDMS composite. The(More)
In this work, gravure printing was used to fabricate a thin film of silver (Ag) nanoparticle ink on flexible polyethylene terephthalate (PET) sheet as an efficient surface enhanced Raman spectroscopy (SERS) substrate. The printed SERS substrate was used for the detection of an explosive organic compound: 2,4-dinitrotoluene (DNT), in vapor phase. An(More)
A stretchable and wearable sensor was successfully screen printed for monitoring human motions. The sensor was fabricated by printing carbon nanotube (CNT) ink on a water-soluble polymer based polyvinyl alcohol (PVA) substrate. The printed sensor was transferred onto the bicep and water was used to dissolve the sacrificial PVA layer. The sensor was(More)
A novel low frequency magneto-electric energy harvester was developed for application in microelectronic devices. The energy harvester was fabricated by screen printing polyvinylidene fluoride (PVDF) ink, as a piezoelectric layer, on flexible and magnetic Metglas<sup>&#x00AE;</sup> substrate. Silver (Ag) ink, as top electrode layer, was then deposited on(More)
