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 […]

Could this next-generation battery technology power the future?

At INL – International Iberian Nanotechnology Laboratory, cutting-edge research is underway to develop next-generation solid-state thin-film lithium-ion batteries. These new batteries could redefine energy storage for wearable electronics, medical implants, IoT devices, and even aerospace technologies. Leading this innovative work is Chadrasekhar Loka, a researcher at Sadewasser group, working towards the PRR New Generation Storage Agenda. Loka is focused on interfacial engineering to overcome some of the toughest challenges in solid-state battery technology. By replacing the traditional liquid electrolyte (the part responsible for many safety risks in conventional batteries) with a solid-state electrolyte, these batteries become significantly safer, more durable, and capable of higher energy densities. Despite their enormous potential, solid-state batteries face several technological hurdles, especially at the interface between electrodes and electrolytes. Poor contact at these interfaces increases resistance, slowing down ion movement and reducing battery performance over time. To tackle these issues, Loka’s work focuses on creating ultra-thin solid electrolytes and precisely tailored electrode surfaces using advanced techniques like Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). These methods allow the creation of layers with nanometre precision, enhancing both ionic conductivity and electrochemical stability, crucial for long battery life and reliable performance under demanding conditions. This […]

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.

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 […]
