In this study, we present a novel capacitive flexible pressure sensor incorporating liquid metal composite-based micropillar dielectric structure. The array was fabricated using UV laser etching, simplified and efficient alternative to conventional lithographic techniques, significantly reducing processing time complexity. To enhance the effective constant variation under applied pressure, incorporated gallium-based (EGaIn), which features low melting point (Tm = 15.5 °C), high electrical conductivity (3.4 × 106 S/m), toxicity. sensitivity range of were systematically analyzed as function EGaIn content aspect ratio (AR). optimized sensor, with 15 vol % an AR 1, demonstrated 2.07 kPa-1 in low-pressure regime (<135 Pa). These results highlight potential proposed for applications requiring high-performance sensing, such electronic skin, augmented/virtual reality systems, health monitoring applications.

Printing techniques have been instrumental in developing flexible and stretchable electronics, including organic light-emitting diode displays, thin film transistor arrays, electronic skins, electrochemical transistors for biosensors neuromorphic computing, as well solar cells with low-cost processes such inkjet printing, ultrasonic nozzle, roll-to-roll coating. The rise of additive manufacturing provides even more opportunities to print electronics automated customizable ways. In this work, we will review the current technologies printing (including printed batteries, supercapacitors, fuel cells, sensors), especially 3D printing. age ongoing AI revolution, application algorithms is discussed terms combining them a future optimization, sustainable design, scalable manufacturing.
