LiMA is a research project at IMB-CNM developing a linear-mode single-photon detector for the visible range based on LGAD technology. Conventional detectors operate in Geiger mode and face limitations such as noise, dead time, afterpulsing, and reduced compatibility with chip-scale integration. LiMA explores proportional photon detection using an innovative high-gain avalanche design that supports low noise and CMOS compatibility, and integrates the detector with silicon-nitride photonic circuits for low-loss light routing. Over a 24-month period, the project will design, fabricate, and demonstrate this approach to enable compact platforms for future quantum and sensing applications.

KICK-IN project aims to develop innovative superconducting read-out devices to enable future ultra-sensitive and scalable quantum detectors. The focus is on the Kinetic Inductance Current Sensor (KICS), a key element of the proposed Single Pixel Superconducting Chip (SPS-Chip) technology. KICK-IN exploits ion irradiation as an advanced nanofabrication technique to locally tune superconducting properties within a single thin film, enabling simplified, reproducible and highly flexible device fabrication. The project will demonstrate the first standalone KICS prototypes, supported by simulations and experimental validation, paving the way for future integration with Transition Edge Sensors and scalable detector arrays. Beyond fundamental physics applications, KICK-IN contributes to the development of superconducting quantum technologies, reinforcing IMB-CNM-CSIC’s role in quantum sensing and cryogenic electronics.

Conventional microbatteries (MBs), either for powering bioelectronic devices or direct actuation, offer passive power delivery but lack the intelligence required for tailored biological actions. In general terms, electrolyte-activated MBs begin operating upon contact with biological fluids, being unable of environmental adaptation and spaciotemporal control. 

STEM aims to radically transform the role of MBs in bioelectronics, from passive to active functional elements capable of environmental adaptation. This project envisions stimuli-enabled microscale batteries whose electrochemical activity is modulated by local biological cues or external stimuli, directly modulating the biological environment or powering low-energy electronics, acting as self-contained (sensor-free and chip-less) smart devices.
