“…This type of actuator achieved an actuation deflection of 80 lm when an electric field of 90 V/lm was applied. An innovative approach for the realization of PVDF-based actuators was presented by Pabst et al [169]. They developed all-inkjetprinted PVDF-TrFE piezoelectric actuators on polyethylene terephthalate (PET) substrates with electrodes printed from silver nanoparticle dispersions for low-cost membrane pumps.…”

Microfluidic devices have not yet evolved into commercial off-the-shelf products. Although highly integrated microfluidic structures, also known as lab-on-a-chip (LOC) and micrototal-analysis-system (lTAS) devices, have consistently been predicted to revolutionize biomedical assays and chemical synthesis, they have not entered the market as expected. Studies have identified a lack of standardization and integration as the main obstacles to commercial breakthrough. Soft microfluidics, the utilization of a broad spectrum of soft materials (i.e., polymers) for realization of microfluidic components, will make a significant contribution to the proclaimed growth of the LOC market. Recent advances in polymer science developing novel stimulus-active soft-matter materials may further increase the popularity and spreading of soft microfluidics. Stimulus-active polymers and composite materials change shape or exert mechanical force on surrounding fluids in response to electric, magnetic, light, thermal, or water/solvent stimuli. Specifically devised actuators based on these materials may have the potential to facilitate integration significantly and hence increase the operational advantage for the end-user while retaining costeffectiveness and ease of fabrication. This review gives an overview of available actuation concepts that are based on functional polymers and points out promising concepts and trends that may have the potential to promote the commercial success of microfluidics.

“…[15][16][17][18][19][20][21][22][23] Ferroelectric Form I (β phase), with an all-trans configuration in P(VDF-TrFE), exhibits the best ferroelectric and piezoelectric properties. A sandwich device prepared using solidstate P(VDF-TrFE) films exhibited both direct and inverse piezoelectric effects.…”

Piezoelectric gels were prepared from low-volatile ionic liquid (IL) 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Emim][TFSI]) gels, and their structural, ferroelectric, and piezoelectric properties were investigated. Poly(vinylidene fluoride-trifluoroethylene) P(VDF-TrFE)/IL gels were formed using thermally reversible physical gels. The structural characterization indicated that the P(VDF-TrFE) molecules in the gels predominantly formed a ferroelectric phase (Form I) of P(VDF-TrFE). Polarization switching peaks were clearly observed using a three-layer stacked device structure. The coercive field of the P(VDF-TrFE)/IL gels substantially decreased to 4-9 MV/m, and their remnant polarizations were maintained at 63-71 mC/m 2 , which is similar to that for typical solid-state P(VDF-TrFE). Finally, the P(VDF-TrFE)/IL gel films exhibited a piezoelectric response, and the highest piezoelectric coefficient was >300 pm/V at an applied voltage frequency of 4 kHz.

“…Organic molecules with π-conjugated structures provide a variety of new materials with metallic and semiconducting properties, attractive for fundamental investigations, engineering applications [1][2][3][4], and as a potential bench mark in nanomedicine or life science products at lab-on-a-chip devices [5]. Although several organic based devices, i.e., organic light emitting diodes (OLEDs) and organic photovoltaics (OPVs), have matured for commercial applications, still a long-standing challenge in molecular electronics relays on doping of organic semiconductors [6][7][8][9][10].…”

In this report, a doped semiconducting ink consisting of a blended poly [2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) with aluminium-tris (8-hydroxychinolin) (Alq3) and diluted in toluene is formulated. The intentional doping with the electron transport nanoparticle Alq3 results in an additional band gap state of the hole transport MEH-PPV polymer and reduction of the switch on voltage of the organic LED display. Doping is probed at room temperature with photoluminescence spectroscopy. Photoluminescence results revealed that as the Alq3 content increases in blends, characteristic peaks of intensities of MEH-PPV are broadened and reduced. In addition, the emission for Alq3 concentrations between 30% and 60% are featured by a band at 565 nm (2.19 eV) for the lower concentration and consistently blue shifted to 530 nm (2.33 eV) for the higher concentration. This new band at 565 nm (2.19 eV) neither belongs to pure MEH-PPV nor to Alq3 and evidences charge transfer from the lowest unoccupied molecular orbital of the Alq3 to the highest occupied molecular orbital of the MEH-PPV.
