“…As shown in Fig. 5(c), this 1.6 mm square pattern of silver V-antennas was built up by loading nine different DMD images and stepping the substrate into a 3 × 3 tile array [38]. Each 540 μm square tile contained antenna elements with 20 μm linewidths that were all transferred with a single laser shot.…”

The use of a digital micromirror device (DMD) in laser-induced forward transfer (LIFT) is reviewed. Combining this technique with high-viscosity donor ink (silver nanopaste) results in laser-printed features that are highly congruent in shape and size to the incident laser beam spatial profile. The DMD empowers LIFT to become a highly parallel, rapidly reconfigurable direct-write technology. By adapting half-toning techniques to the DMD bitmap image, the laser transfer threshold fluence for 10 μm features can be reduced using an edge-enhanced beam profile. The integration of LIFT with this beam-shaping technique allows the printing of complex large-area patterns with a single laser pulse.

“…The use of spatial light modulators, based on commercial digital micromirror devices (DMDs), makes possible the dynamic adjustment of the size and shape of the laser pulse and thus the ability to print reconfigurable congruent voxels [58,59]. The high refresh rate (kHz) of the DMD thus enables the printing of different patterns with each laser shot.…”

“…40 LIFT has been recently employed to print high viscosity pastes that reproduce the shape of the laser spot. [41][42][43][44][45][46][47] This process, referred to as laser-decal transfer, offers a new approach to direct-writing techniques, in which voxel shape and size become controllable parameters, allowing the generation of thin-film like structures for a wide range of applications, such as 3-D interconnects, metamaterials, free-standing structures, membranes, and circuit repair. The ability to modify the voxel shape and size according to the desired final pattern allows an increase in the resolution and speed of the printing process.…”

“…Details of the LIFT process have been described elsewhere. [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] In the electrode formulation, graphite (KS6) is added to improve the electric conductivity and carbon black (Super P) is added to increase the porosity in the electrode films. The polyvinylidene fluoride hexafluoropropylene (PVDF-HFP) is used as a binder to hold the electrode films onto current collectors.…”

This paper reviews recent work on the fabrication of energy storage and power generation using laser-based processes such as pulsed laser deposition (PLD), laser-induced forward transfer (LIFT), and laser surface processing techniques. PLD is a versatile technique for depositing high-quality layers of materials for cathodes, anodes, and solid electrolytes for thin-film microbatteries. Using sequential PLD processes, solid-state thin-film lithium-ion microbatteries can be successfully fabricated. LIFT is a powerful tool for printing complex materials with highly porous structures for the fabrication of micropower sources such as thick-film batteries and metal oxide-based solar cells. In particular, using the LIFT process it is possible to print thick layers (∼100 μm) while maintaining pattern integrity and low-internal resistance. As a consequence, power sources fabricated in this manner exhibit higher energy densities per unit area than those obtained by traditional thin-film growth techniques. In addition, the printed active materials can be modified by postlaser processes, such as laser sintering and laser structuring, to further improve the device performance by enhancing the electrodes' three-dimensional networked structure and increasing the overall active surface, respectively. This review will discuss various examples where laser materials' processing has led to new approaches in the development of micropower sources applications. © The Authors.
