Micro and nano-devices

The multifunctional materials, nanostructures and surfaces being developed, allow the implementation in functional prototypes demonstrating the suitability of the materials for advanced applications. Thus, radiofrequency instrumentation is being implemented for MRI, hyperthermia, and wideband ferromagnetic resonance applications. Force, deformation, magnetic, magnetostrictive and chemical sensors are being fabricated, among others. In addition, the study and implementation of printed and flexible electronic devices is being used for applications in areas such as wearables, point of care devices, interactive surfaces and structural health monitoring.

del Campo García, Francisco Javier Ikerbasque Research Professor
Email: Javier.delcampo@bcmaterials.net

F. Javier del Campo graduated in Analytical Chemistry from Stratchlyde University (1998) and the University of the Basque Country (1999). He obtained a DPhil from the University of Oxford in 2003, where he specialized in Electrochemistry. After 18 months in industry, developing Electrochemistry-based process solutions for international companies and government agencies, he joined the Spanish National Microelectronics Centre, where he further specialized in miniaturization and systems integration, covering a number of fabrication technique including microfabrication, conventional manufacturing processes and screen printing with a focus on prototype development methodologies. During this time, his research involved the miniaturization of electrochemical sensors and biosensors for environmental and health applications, particularly in the area of point of care devices.

His most recent activities have focused on the development of self-powered sensors based on electrochromic materials, as a means to avoid the need for silicon-based components, which earned him a Leonardo grant from the BBVA Foundation in 2016.

To date, Javier has co-authored over 100 scientific publications (h=29), is co-inventor in 8 patents and has supervised 7 PhD theses.
He is now Ikerbasque research professor leading the Micro- and Nano- devices line at BCMaterials.

Current research interests include: Electrochemistry, microfluidics, sensors and biosensors, miniaturization techniques, and systems integration.
