Adv. Funct. Mater.: MXene Micro-Supercapacitors Fabricated via Aerosol Jet Printing for Flexible, Washable Textile Energy Storage

With the rapid advancement of technology, smart wearable devices are becoming increasingly ubiquitous. Our daily lives, sports activities, health monitoring, and even personal safety all rely on these “smart garments.” However, to achieve truly “intimate” smart functionality, one key challenge is solving the energy‑supply problem: conventional batteries are bulky, rigid, and difficult to integrate into soft textile materials, while their lifespan, charge‑discharge performance, and wash durability all pose significant hurdles. Consequently, developing lightweight, flexible, washable energy storage devices with superior performance has emerged as a crucial breakthrough for advancing the smart‑wearable industry. Supercapacitors, with their high power density, long cycle life, and rapid charge‑discharge capabilities, stand out as an ideal choice. Integrating supercapacitors directly into textiles has thus become the industry’s ultimate goal. Today, we introduce an exciting technological breakthrough: using aerosol jet printing (AJP) to directly “print” high‑performance MXene materials onto fabrics, creating miniature supercapacitors that are both soft and washable, while delivering exceptional performance—ushering in a new era for wearable electronics.

ACS Appl. Energy Mater.: 3D Aerosol-Jet-Printed Graphene Micro-Supercapacitor Arrays: Achieving High Voltage and High Integration Density with Hollow-Cylinder Electrodes

When you’re exercising with a smartwatch, do you often worry about the battery suddenly running out? And as IoT sensors become ubiquitous in homes and cities, how can we provide these tiny devices with a long-lasting, reliable power supply? With the explosive growth of portable and wearable electronics and IoT technologies, the limitations of traditional energy-storage devices—such as miniaturization, high integration, and flexibility—are becoming increasingly apparent. Recently, research teams from institutions including the Guangdong–Israel Institute of Technology and the Southern University of Science and Technology published a groundbreaking achievement in ACS Applied Energy Materials. Using aerosol-jet 3D printing technology, they successfully fabricated an array of graphene‑based hollow‑pillar electrode (HPE) microsupercapacitors (MSCs). These devices not only deliver a high output voltage of 10 V but also boast an exceptionally high integration density of 102 cm⁻², while maintaining excellent bending stability, thus opening up new avenues for the development of miniature energy‑storage devices.

With the rapid advancement of 3D printing (additive manufacturing) technology, demand for high-performance metal powders continues to grow, particularly in sectors such as aerospace, automotive, and medical industries. As a next-generation metal powder, titanium-based composite powders have become a research hotspot due to their excellent properties, including light weight, high strength, and corrosion resistance.

Femtika Laser Nanofactory MPP Multiphoton Polymerization

Introduction to Multiphoton Polymerization: Multiphoton polymerization (MPP) is a 3D printing technique capable of fabricating polymer structures of arbitrary shapes with sub-micron resolution. First, a polymer material mixed with a photoinitiator is dispensed onto a glass slide and pre‑baked to form a photoresist layer. A laser direct‑write process is then employed to create 3D microstructures. Under laser irradiation, the polymer hardens at the irradiated sites through a process known as photopolymerization. Finally, the microstructure is immersed in an organic solvent to develop the unexposed photoresist. MPP is commonly used in the fabrication of microelectronic devices because it enables the creation of extremely small, high‑precision features. Moreover, thanks to the highly focused beam, it can produce complex 3D geometries. Equipment Parameters: Additive manufacturing materials include SZ2080, SU‑8, Ormocers, Glassomer, hybrid organic–inorganic materials, photopolymers, elastomers, and proteins. Minimum XY feature size: 150 nm; minimum surface roughness: Ra ≤ 20 nm; maximum build speed: 30 mm/s. Key Advantages: ● Nanoscale‑resolution additive manufacturing technology ● True 3D microstructures at the micrometer scale ● Wide range of available polymers ● Error‑free, seamless fabrication

Femtosecond lasers are highly versatile tools that can be employed in a wide range of microfabrication processes. Each process has specific requirements regarding the laser, beam delivery, and material properties. Our laser nanofabrication workstation enables hybrid manufacturing, meaning that multiple processes can be supported by the same equipment. The two most commonly used techniques are multiphoton polymerization and selective glass etching, but these are far from the only ones! By precisely tuning its parameters, the same machine can perform an even broader array of processes.

SU-8 photoresist

The SU-8 3005 series of photoresists are negative-tone resists formulated with cyclopentanone as the solvent. In ultra-thick-film coating processes, they deliver excellent pattern stability and high resolution. Moreover, their film-thickness range is broader than that of any other commercially available photoresist: a single spin-coating step can produce films ranging from 0.5 to 300 μm in thickness, and multiple spin-coatings can be performed as needed to achieve even thicker films.
