Softening neural probes

Mechanically adaptive thiolene-acrylate based neural probes which change their elastic modulus under physiological conditions to mitigate neuroinflammatory response.

Infrared neural stimulation

Multimodal silicon microelectrodes to excite or inhibit single unit activity through local irradiation of infrared light.

Drug delivery probes

Monolithically integrated microfluidic channels in a silicon multielectrode for local drug delivery in the brain tissue.

Flexible, intracranial implants

Polyimide and Parylene based microECoG electrodes designed for cortical electrophysiology and simultaneous optical and MR imaging of the intact brain.

The Research Group of Implantable Microsystems is hosted by the Faculty of Information Technology & Bionics, PPCU, Budapest, Hungary. The objective of our group is to act as a link between material science and neuroscience and to develop cutting-edge technologies to investigate brain structure and function. Our multidisciplinary team, composed of electrical, chemical, bionic engineers and biologists devotes its research to introduce novel materials in neural applications and to construct multimodal microdevices facilitating simultaneous use of various functionalities like electrical recording, local drug delivery and optical stimulation. In cooperation with domestic and international labs, we develop flexible, implantable devices, which are compatible with neuroimaging techniques like MRI and two-photon imaging. Our works rely on cleanroom processes provided by the Microsystems Lab of CER, HAS.
