Summary: The authors propose laser printing as a facile process for fabricating printed electronics with minimum feature sizes below 1μm and demonstrate functional diodes, memristors, and physically unclonable functions. Laser printing with different inks, for the semiconductor ZnO and the metals Pt and Ag, is introduced for fabricating printed functional electronic devices with minimum feature sizes below 1μm. The versatility of this approach is demonstrated by showing functional diodes, memristors, and a physically unclonable function.

Summary: The effects of thermal annealing on screen-printed NiO electrodes for asymmetric battery-type supercapacitors on flexible substrates were investigated. Six morphologically diverse NiO samples were obtained by synthesizing and annealing Ni(OH)2 at different temperatures. The NiO annealed at 400 degrees C demonstrated the highest areal capacitance of 19.54 mF/cm2 and reduced charge-transfer resistance, which was consistent with its highly porous yet continuous structure. An inter-digital asymmetric supercapacitor with NiO-400 cathode and graphene anode exhibited high areal capacitance of 26.42 mF/cm2, a wide potential window of 1.5 V (at 97.3% coulombic efficiency), and excellent flexibility with 96.4% retention (180 degrees) after 1000 cycles.

Summary: We present the fabrication of a fully printed, lead-free, polymer piezoelectric transducer and demonstrate the characterization of its structural, dielectric, and ferroelectric properties at different processing stages. The performance of the transducer made with poly(vinylidene fluoride-trifluoroethylene) is evaluated through resonance frequency analyses, acoustic power measurements, and pulse-echo experiments. Importantly, we demonstrate an optimal performance in the medical ultrasound range (<15 MHz) with acoustic power >1 W cm(-2) for the first time in a fully printed transducer, which shows promise for applications in epidermal and wearable electronics. Overall, these findings lay a strong foundation for future research in the field of flexible ultrasound transducers.

Summary: The traditional manufacturing processes for optical sensors have limitations, but 3D printing offers a new way to create optical devices with added functionalities like spectral color variation in lenses. By optimizing DLP 3D printing parameters and mixing thermochromic pigment powders in resins, customized tinted Fresnel lenses can be fabricated for selective color focusing and temperature sensing applications. The surface wettability of the lenses can be determined through contact angle measurements, showing the potential for custom-built optical devices with active and passive sensing capabilities.
