IJAMT, Cambridge, UK and Harvard Medical School: A high-temperature microsensor fabricated via aerosol jet printing of colloidal platinum nanoparticle ink enables continuous condition monitoring of rocket engine structures.

In the aerospace field, the reliability and safety of rocket engines are of paramount importance. Conventional monitoring methods rely on manual inspections, making it difficult to capture structural deformations in high-temperature environments in real time. Recently, a technology known as Aerosol Jet Printing (AJP) was featured in the International Journal of Advanced Manufacturing Technology. Using this technique, scientists directly printed platinum‑nanoparticle ink microsensors—capable of withstanding temperatures up to 1290°C—onto the surface of rocket engines, enabling real-time monitoring of structural strain and creep. This article will systematically examine its underlying principles, applications, and future prospects.

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.
