CHARM3D paves the way for the efficient printing of free-standing 3D structures that offer high electrical conductivity, self-healing capabilities and recyclability — a boon for electronics in healthcare, communications and security

SINGAPORE, July 29, 2024 /PRNewswire/ — Unlike traditional printed circuit boards, which are flat, 3D circuitry enables components to be stacked and integrated vertically — dramatically reducing the footprint required for devices.  Advancing the frontiers of 3D printed circuits, a team of researchers from the National University of Singapore (NUS) has developed a state-of-the-art technique – known as tension-driven CHARM3D – to fabricate three-dimensional (3D), self-healing electronic circuits. This new technique enables the 3D printing of free-standing metallic structures without requiring support materials and external pressure.

The research team led by Associate Professor Benjamin Tee from the Department of Materials Science and Engineering in the NUS College of Design and Engineering used Field’s metal to demonstrate how CHARM3D can fabricate a wide range of electronics, allowing for more compact designs in devices such as wearable sensors, wireless communication systems and electromagnetic metamaterials.

In healthcare, for instance, CHARM3D facilitates the development of contactless vital sign monitoring devices — enhancing patient comfort while enabling continuous monitoring. In signal sensing, it optimises the performance of 3D antennas, leading to improved communication systems, more accurate medical imaging and robust security applications.

The team’s findings were published in the journal Nature Electronics on 25 July 2024. Assoc Prof Tee is the corresponding author of the research paper.

A more streamlined approach to 3D circuit manufacturing

3D electronic circuits increasingly underpin modern electronics, from battery technology to robotics to sensors, enhancing their functionalities while enabling further miniaturisation. For example, 3D architectures, with their large effective surface areas, improve battery capacity and enhance sensor sensitivity.

Direct ink writing (DIW), a promising 3D printing technique currently used to fabricate 3D circuits, poses significant drawbacks. The crux lies in its use of composite inks, which have low electrical conductivity and entail support materials to aid in solidification after printing. The inks are also too viscous, limiting printing speed.

Enter Field’s metal, a eutectic alloy of indium, bismuth and tin. Eutectic alloys melt and freeze at a single temperature lower than the melting points of their constituent metals — offering an attractive alternative material for 3D printing. With a low melting point of 62 degrees Celsius, a high electrical conductivity and low toxicity, Field’s metal, unlike composite inks, solidifies rapidly — a crucial characteristic that enables the printing process to eschew support materials and external pressure.

Leveraging the low melting point of Field’s metal, the CHARM3D technique exploits the tension between molten metal in a nozzle and the leading edge of the printed part, culminating in uniform, smooth microwire structures with adjustable widths of 100 to 300 microns, roughly the width of one to three strands of human hair. Critically, phenomena such as beading and uneven surfaces — characteristic of pressure-driven DIW — are also absent in CHARM3D.

Compared to conventional DIW, CHARM3D offers faster printing speeds of up to 100 millimetres per second and higher resolutions, offering greater level of detail and accuracy in circuit fabrication. CHARM3D forgoes post-treatment steps and enables the fabrication of complex free-standing 3D structures, such as vertical letters, cubic frameworks and scalable helixes. Moreover, these 3D architectures exhibit excellent structural retention with self-healing capabilities, meaning they can automatically recover from mechanical damage and are recyclable.

“By offering a faster and simpler approach to 3D metal printing as a solution for advanced electronic circuit manufacturing, CHARM3D holds immense promise for the industrial-scale production and widespread adoption of intricate 3D electronic circuits,” said Assoc Prof Tee.

Far-reaching applications

The researchers successfully printed a 3D circuit for wearable battery-free temperature sensors, antennas for wireless vital sign monitoring and metamaterials for electromagnetic wave manipulation — capturing the diversity in applications enabled by CHARM3D.

Traditional hospital equipment such as electrocardiograms and pulse oximeters require skin contact, which can cause discomfort and risk infections. Through CHARM3D, contact-free sensors can be integrated into smart clothing and antennas, providing continuous, accurate health monitoring in hospitals, assisted-living facilities or home settings.

Furthermore, arrays of 3D antennas or electromagnetic metamaterial sensors — fabricated via CHARM3D — could optimise signal sensing and processing applications. This leads to improved signal-to-noise ratios and higher bandwidths. The technique opens up the possibility of creating specialised antennas for targeted communication, enabling more accurate medical imaging, such as microwave breast imaging for early tumour detection, and advanced security applications, such as detecting hidden devices or contraband emitting specific electromagnetic signatures.

Other collaborators in this work include Dr Zhuangjian Liu from Agency for Science, Technology and Research’s Institute of High Performance Computing and Professor Michael Dickey from North Carolina State University’s Department of Chemical and Biomolecular Engineering.

Next steps

The research team envisions that this technique can be extended to other types of metals and structural applications. The team is also looking for opportunities to commercialise this unique approach for metal printing.

DeepKeep Demonstrates Superior Multilingual AI Security Performance in New Benchmark Study

Published

on

By

As the gap in the multilingual security of AI guardrails grows, new benchmark research reveals that DeepKeep’s ability to detect prompt injection and PII across languages outperforms others, including Meta and Nvidia

TEL AVIV, Israel, July 22, 2026 /PRNewswire/ — DeepKeep, the end-to-end AI security platform, today unveiled the results of a new benchmark study showcasing significant improvements in the performance and efficiency of its multilingual AI security solution. The research study compared DeepKeep’s approach to other guardrails and LLM-as-a-Judge methods and demonstrated that DeepKeep’s multilingual capability provides superior accuracy and consistency.

As organizations deploy AI tools across global teams, the prompts and interactions these systems process increasingly span multiple languages. However, many AI security systems today are designed primarily for English-language prompts, and the consequences are measurable. A Brown University study found that translating unsafe inputs into low-resource languages got GPT-4 to engage with harmful requests 79% of the time, versus under 1% in English. As enterprises deploy AI globally, attackers can exploit this gap by issuing malicious prompts in other languages to bypass guardrails. While translation-based security solutions exist, these often introduce latency, lose context, or produce inconsistent results across languages, creating a growing security blind spot for multinational enterprises.

DeepKeep directly analyzes the semantic meaning of prompts and responses across languages using a cognition-based analysis, allowing the system to classify data without translating it into English first. The cognition-based solution can deliver an interpretable response, allowing the system to learn and improve in time. Due to their design, DeepKeep’s guardrails can efficiently handle zero-day attacks. The guardrails are also designed to handle mixed-language prompts seamlessly – a scenario increasingly common in enterprise environments where users combine multiple languages within a single AI query.

In benchmark testing against widely used open source models, including Meta’s LLaMa Prompt Guard and Nvidia’s NeMo, DeepKeep significantly outperformed in detecting prompt injection attempts and Personal Identifiable Information (PII).

The evaluation used several widely recognized prompt injection datasets, including SafeGuard, Wild Jailbreak, and Alpaca, with test sets translated into 12 additional languages including Japanese, German, Spanish, French, Italian, Korean, Dutch, and Portuguese. Across these benchmarks, DeepKeep achieved F1 scores approaching 0.98 in prompt injection detection while significantly reducing false negatives compared to translation-based guardrail models.

The platform maintains consistent security decisions across languages while operating with smaller, more efficient model architecture. DeepKeep’s multilingual classifier operates with a model of roughly 400 million parameters, which is significantly smaller than many guardrail models that rely on multi-billion-parameter architectures, enabling faster inference and lower latency in enterprise deployments.

“AI security has largely been built around the assumption that prompts are written in English or that translation is sufficient. That assumption no longer reflects how enterprises actually use AI,” said Yossi Altevet, CTO and Co-Founder at DeepKeep. “As AI systems are deployed across global teams and markets, security models must understand intent across languages, not just words. That shift requires a fundamentally different approach to how AI interactions are analyzed and protected, and we’re proud to have created a solution that meets this challenge with flying colors.”

DeepKeep’s multilingual security solution is part of the company’s established suite of enterprise AI security solutions that give businesses the confidence to leverage AI without sacrificing safety, control, or trust.
