Recent Advances in Programmable Surface Systems: A Material–Mechanism–Structure Perspective

Pius Soh, Hyein Jung, Jin-Tae Kim

J. Flex. Print. Electron. 2025;4(1):31-54.
https://doi.org/10.56767/jfpe.2025.4.1.31

Recent advances in programmable surface systems have opened new possibilities in stretchable electronics, where surfaces can actively morph their geometry and functionality in response to external stimuli. This review reports recent developments around three central pillars: functional materials, actuation mechanisms, and geometric design strategies. This framework allows for a unified understanding of how shape-morphing behavior emerges from the interplay between material composition and mechanical design, and it provides insights into how to ...

https://doi.org/10.56767/jfpe.2025.4.1.99

Continuous monitoring of hydrostatic and interstitial fluid pressures within biological tissues is essential for diagnosing and managing a wide range of medical conditions, including hydrocephalus, glaucoma, compartment syndrome, and tumor progression. However, conventional pressure sensors are typically rigid and invasive, limiting their applicability for long-term implantation in soft tissue environments. In this study, we present a flexible, capacitive pressure sensor based on a porous polydimethylsiloxane (PDMS) matrix embedded with barium ...

Anionic Conjugated Polyelectrolyte as a Multifunctional Interfacial Layer for Defect Suppression in Perovskite LEDs

Bum Chan Park, Rahmatia Fitri Binti Nasrun, Jihoon Kim, Dong Hwan Son, Hyun-Seock Yang, Joo Hyun Kim, Bo Ram Lee

J. Flex. Print. Electron. 2025;4(1):109-123.
https://doi.org/10.56767/jfpe.2025.4.1.109

Nickel oxide (NiOx) is widely used as a hole transport layer in perovskite light-emitting diodes (PeLEDs) due to its suitable energy level alignment, high transparency, and stability. However, its surface typically contains inhomogeneous oxygen vacancies and abundant hydroxyl groups, leading to interfacial energy mismatches and defect formation that hinder efficient charge injection and limit device performance. To address these challenges, we introduce a dual-passivation strategy employing an anionic conjugated polyelectrolyte (CPE), Poly[9,9-...

Low-Voltage n- and p-Channel Organic Transistors using Al₂O₃ Dielectric

Walid Boukhili, Swelm Wageh, Chee Leong Tan, Huabin Sun, Dongyoon Khim

J. Flex. Print. Electron. 2025;4(1):137-149.
https://doi.org/10.56767/jfpe.2025.4.1.137

The integration of high-k dielectric materials presents a promising strategy to reduce the operating voltage of organic thin-film transistors (OTFTs) while enhancing their overall performance. In this study, we explore the impact of a 20 nm Al2O3 interlayer deposited atop conventional SiO2 dielectrics on the electrical characteristics of both p-channel pentacene and n-channel N,N′-dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) OTFTs. Devices incorporating the Al2O3/SiO2 bilayer dielectric demonstrate marked improvements in electrical prope...
