Magnetorheological elastomers (MREs) are soft magnetic composites that achieve tunable changes in stiffness and damping the presence of a field. Rigid particle composite (RC) MREs have been studied for decades their potential applications to automotive dampers robotic systems. Recently, fluid (FC) developed which utilize fluids as inclusions elastomers. An investigation into how inclusion phase affects magneto-mechanical performance may greatly improve MRE design capabilities. Here we...
Abstract Soft pumps are a crucial element in biology, from our own hearts to actuators driving the motion of many creatures nature. For example, squid is one fastest and most powerful animals ocean despite being almost entirely soft, using controlled jets by compressing an internal chamber propel itself rapidly through water. Duplicating this performance artificial system has, however, remained challenging. Here, novel soft electromagnetic pump based on coils room temperature LM (liquid...
Micromolding silicone elastomers has many uses in microfluidics, soft lithography and microfabrication but usually requires further processing to integrate functional materials like electrodes. Herein, we report a simple method pattern electrodes into micromolded by using laser-induced graphene (LIG) on SU-8, which is popular photoresist. LIG derived from SU-8 generates conductive carbon layer that transfers the cured elastomer when peeled away mold, producing microchannels with embedded We...
Herein the electrical and microstructural characterization of additively manufactured glassy carbon fabricated via two‐photon polymerization (2PP) is reported. Thermal decomposition at elevated temperatures volatizes much 2PP part, converting crosslinked photopolymer into a carbon‐rich structure. Upon heating to continued material becomes increasingly conductive. The ability control conductivity pyrolyzed done by varying pyrolysis temperature, with maximum obtained roughly 2 × 10 4 S m −1 ....
Abstract Room‐temperature eutectic Gallium Indium (eGaIn)‐based devices offer stretchable, conductive, and reconfigurable properties for robotics, communications, medicine. Microfluidics enables eGaIn device creation, but these typically have larger feature sizes. Recent three‐dimensional (3D) printing advancements, particularly direct laser writing (DLW), allow sub‐100 µm microfluidic devices. However, interfacing DLW microfluidics with systems poses challenges in channel resist removal,...
Nickel metal foams serve as both a substrate and bottom electrode for dielectric capacitor using atomic‐layer deposition (ALD) eutectic gallium–indium (EGaIn) liquid (LQM) counter electrode. The conformal has composition of 6.25% Al–HfO 2 in the antiferroelectric phase, confirmed with polarization versus electric field measurements. Liquid EGaIn is pressure‐infiltrated within coated to form capacitor. Capacitances up 4 μF are realized. Calorimetry infiltrated shows 60 J g −1 latent heat upon...
