Abstract Direct printing of functional inks is critical for applications in diverse areas including electrochemical energy storage, smart electronics and healthcare. However, the available printable ink formulations are far from ideal. Either surfactants/additives typically involved or concentration low, which add complexity to manufacturing compromises resolution. Here, we demonstrate two types two-dimensional titanium carbide (Ti 3 C 2 T x ) MXene inks, aqueous organic absence any additive...
Abstract The fast growth of portable smart electronics and internet things have greatly stimulated the demand for miniaturized energy storage devices. Micro‐supercapacitors (MSCs), which can provide high power density a long lifetime, are ideal stand‐alone sources microelectronics. However, relatively few MSCs exhibit both areal volumetric capacitance. Here rapid production flexible is demonstrated through scalable, low‐cost stamping strategy. Combining 3D‐printed stamps with arbitrary...
Maximizing the energy and power density of supercapacitors requires thick electrodes, enabling a high areal loading. Simultaneously, sophisticated, hierarchical pore structure for active material is needed, granting accessibility electrons ions. However, porosity thickness need to be carefully balanced maximize while ensuring performance. Here, we show that by forming electrodes from Ti3C2Tx 2D nanosheets in form interconnected 3D networked thin films (up ∼220 nm), can fabricate performance...

Many applications of MOEMS microscanners rely on accurate position feedback. For devices which do not have intrinsic on-chip feedback, information can be provided with optical methods, most simply by using a reflection from the backside scanner. By measuring intensity distribution reflected beam across quadrant diode, one precisely detect mirror's deflection angles. Previously, we presented sensing device, applicable to arbitrary trajectories, is based measurement laser diode. In this work,...
