Smart garment for real‑time 3D monitoring of scoliosis

A smart garment integrating innovative textile sensors to measure, in real time, the progression of scoliosis, without rigid components or ionizing imaging. Soft and non‑invasive, it allows continuous monitoring of spinal curvature and brace effectiveness.

This innovation addresses a major limitation of current practices, which still rely heavily on periodic X‑rays, exposing adolescents to repeated radiation and providing only a limited, momentary view of postural evolution.

Passive earplugs offering natural perception of one’s own voice

These earplugs use advanced acoustic architecture to reduce external noise without amplifying internal sounds, including the user’s own voice. Ambient noise is attenuated while the voice remains natural—without resonance or muffled sensation. Acoustic comfort is significantly improved, and communication remains clear. The technology is fully passive, integrated directly into the earplug, and is currently deployed in earplugs developed by PhonicLab.

High-precision MEMS clock

This innovative MEMS clock combines a micro-oscillator and an extremely accurate temperature control system on a single silicon chip. Until now, this level of frequency stability was reserved for much larger and more power-hungry electronic systems. Being compact and energy-efficient, the technology can meet the needs of critical systems in telecommunication, geolocation (GNSS), data centres, and high-precision instrumentation.

This invention solves a major problem affecting existing high-precision clock components, which require bulky, energy-intensive, thermally-insulated housings to maintain their stability. With an integrated silicon solution, achieving similar performance in a considerably more compact format is now possible.

Printing photocatalytic surfaces for water treatment

Metal oxide-based active surfaces that decontaminate industrial water using light. Inktio has developed this innovative technology, which enables the crystallization of certain metal oxides, such as titanium dioxide, when exposed to visible light while consuming far less energy than conventional thermal processes.

This innovation addresses a major challenge in water treatment: producing high-performance photocatalytic surfaces on a large scale, while lowering the energy costs associated with their production. This technological breakthrough means it’s now possible to print these surfaces on plastic materials, facilitating industrialization of the technology and paving the way for new solutions to water-related environmental challenges.

The technology was developed by Jaime Benavides, Luis Felipe Gerlein Reyes, and Astrid Carolina Angel Ospina, with scientific support from Professor Sylvain Cloutier.
