Integrated Micro and Nano Technologies (IMiNa)
The IMiNa research group develops applied research on polymeric and silicon-based micro-electromechanical systems (MEMS), inkjet-printed sensors, gas and passive sensors, micro-opto-electromechanical systems (MOEMS), diffractive optics, and microlenses. We also work on advanced integration technologies, such as microfabrication process integration, microfluidics integration, and packaging.
