Imec-NL is an independent research center and together with TNO one of the pillars in the Holst Centre. Its research focuses on the next generation of wireless autonomous transducer solutions. Imec research bridges the gap between fundamental research at universities and technology development in industry. And tries to reinforce the local industry, and to collaborate intensively with local universities. Imec integrates key building blocks to realize solutions for the future deployment of autonomous wireless transducer networks. Key application areas are targeted from potential user domains such as medical and lifestyle, industrial process monitoring & control, agriculture, mobile gaming, automotive, home and industrial buildings, transportation/logistics/asset management. Imec’s patent portfolio covers process technology exploration, ultra‐low power communication, components such as ADCs, amplifiers, systems, energy scavenging, sensors, microfluidics and algorithms.

Role in the NexGen Project

Holst Centre/imec develops in NexGen a miniaturized multi-ion sensor system. This system will simultaneously measure multiple ion levels in a small amount of fluid. The initial target is to measure pH, chloride, sodium and potassium levels, but the platform’s functionality can be extended to other ions. The sensing mechanism is based on solid-state or screen-printed electrodes covered by ion-selective membranes. In NexGen, the focus is on accurately determining the sodium and potassium level in bodily fluids. The ion sensor’s performance will be tested in the lab and under application conditions. This will be complemented with analysis of long-term stability, readout electronics, calibration, and algorithm development.
