Taking inspiration from the human brain to create a new class of intelligent, light-powered devices

At INL, our researchers are pushing the boundaries of brain-inspired computing, developing neuromorphic systems that process sensory data the way nature does – fast, efficiently, and with minimal energy. In a recently published paper in Scientific Reports, INL researchers developed a tiny micropillar quantum resonant tunnelling diode, or RTD, that behaves like a sensory neuron. This ‘neuron’ is capable of detecting light, processing information, and converting it into electrical signals, all within a single nanoscale device. Researcher Bruno Romeira explains, “This is possible because we are using quantum phenomena.” At its core, this system is a III–V semiconductor structure (materials widely used in photonics and high-speed electronics) designed to respond directly to incoming near-infrared light. When the light intensity reaches a certain threshold, the device enters a state known as negative differential resistance, triggering large-amplitude voltage oscillations. In other words, the incoming light signal is transformed into rhythmic electrical bursts, just like the firing patterns seen in biological neurons. Traditional neuromorphic hardware often relies on complex circuits, combining separate memory components and oscillators to mimic the way biological neurons process information. This increases the size, power consumption, and complexity of the system. The new device developed by Bejoys Jacob and […]

INL Hosts Insightful Session with Professor Manuel Heitor on European Research and Innovation

On Friday, February 28th, INL had the distinct privilege of welcoming back Professor Dr. Manuel Heitor, former Minister of Science in Portugal (2015-2022), an important figure following closely the conception, growth, and continued success of INL. Professor Heitor addressed a nearly full auditorium, sharing his profound insights into the dynamic evolution of research and innovation across Europe. The discussion revolved around the “Align, Act, Accelerate (AAA) Report,” which critically examines the current and emerging challenges facing European research and innovation. The report offers strategic recommendations to refine European funding frameworks, ensuring adaptability within an increasingly complex and fast-paced global landscape. The AAA Report has garnered significant attention and endorsement from leading publications, including Times Higher Education and Science Business. Professor Heitor’s ongoing efforts, such as coordinating the workgroup that delivered the AAA Report, or the survey for CESAER, further reinforce his pivotal role in shaping European research and innovation strategies. Science for PolicyProfessor Heitor’s presentation provided an extensive analysis of the key themes explored in the AAA Report, with a strong emphasis on “science for policy”—the integration of scientific knowledge into policymaking to drive forward-looking strategies in times of transformation. One of his central messages was to “Choose Europe,” advocating […]

INL Colloquia 2025: Igniting Monthly Innovation, Uniting Scientific Minds

INL proudly introduces the INL Colloquia Series 2025, an inspiring monthly event that delves into groundbreaking advances in science and engineering. More than just a new theme, it’s about bringing together high-level, inspiring researchers who push the boundaries of their fields. Each month, a new theme will be explored, inviting fresh perspectives and fostering an environment where innovation and curiosity can thrive. Open to the general public, the series aims to unite experts, students, and enthusiasts alike to share in the excitement of scientific discovery. In this inaugural session, Professor David Gracias of Johns Hopkins University presents his visionary talk, “Physical Intelligence at the Interface of Biology and Engineering.” His research challenges traditional boundaries by applying micro and nanoscale patterning techniques—originally developed for semiconductors and rigid materials—to hydrogels and living cells. This pioneering work lays the foundation for future technologies such as adaptive implants, living robots, and smart devices that merge engineered precision with the dynamic qualities of biological systems. Professor Gracias’ innovative efforts include the development of shell microelectrode arrays for brain organoids and the creation of biocompatible processes to pattern live cells with nanolithographic arrays. These advancements not only highlight the transformative potential of merging biology with technology […]

INL Develops High-Speed Nanosecond True Random Bit Generator for Secure Computing

The International Iberian Nanotechnology Laboratory (INL) has developed a Nanosecond True Random Bit Generator (nRBG), on an advanced solution for secure randomness in cryptographic systems, artificial intelligence (AI), and high-performance computing (HPC). The nRBG technology operates at the nanoscale and delivers true random numbers at a speed of one bit every 10 nanoseconds, making it one of the fastest and most reliable random number generation solutions available today. Its high entropy and unpredictability have been validated through 10 National Institute of Standards and Technology (NIST) randomness tests, ensuring its suitability for critical security applications. Advancing Computing with True Randomness Random number generation is a fundamental component of digital systems, particularly in encryption, communications, and AI-driven models. Unlike other generators, which rely on deterministic algorithms, INL’s nRBG generates unpredictable, high-speed random bit streams, enhancing efficiency across various domains. Key features of INL’s nRBG include: Potential Applications: INL’s nRBG is designed to support a range of high-security and computational applications, including: INL partners with technology companies, research institutions, and industry leaders to explore: technology integration – embedding the nRBG into existing and emerging security architectures; joint research and development (R&D) – advancing next-generation randomness solutions for AI, quantum computing, and cybersecurity; and commercialisation pathways – bringing nRBG technology to market-ready applications. Organisations interested in integrating nRBG […]

Can Earth’s gravitational field monitor climate change?

The measurement of our planet’s gravitational field, known as gravimetry, allows us to extrapolate the rate at which climate changes are occurring by detecting small variations in Earth’s gravitational field, caused, for example, by melting ice. Inês Sofia Garcia, a Research Engineer at INL, is focused on the development of a high-precision MEMS (micro electromechanical system) accelerometer, crucial for detecting the gravity field shifts of our planet. This accelerometer is a system capable of converting a mechanical phenomenon into an electrical one, and vice versa, transforming an electrical signal into a mechanical displacement. “Our group is creating a MEMS accelerometer to measure Earth’s acceleration changes,” explains Inês Garcia. “We handle the system’s modelling, design, fabrication, and characterisation.” With rigorous demands for stability, power management, and satellite orientation accuracy, this research work strengthens Portugal’s position in the global space sector. The team developed the device as part of the uPGRADE project, and at INL, we are already looking ahead to its next phase: uPGRADE-NEXT. In this new project, the device will undergo space qualification and is set to be included in the first uPGRADE microsatellite launch, planned for mid-2026. These flagship projects, led by Rosana Dias and Filipe Alves, will also […]
