3D-impaction printing of porous layers

Porous layers composed of nanoparticles (NPs) have a wide range of (potential) applications including catalysts, (chemical) sensors, thermoelectric materials and electronics. These application domains will profit strongly from our NP printing process which is flexible with respect to i) the composition of the NPs and ii) the possibility of...

Towards an Active Graphene-PDMS Implant

Neural interface in the form of microelectrodes are used to monitor and treat spinal cord injury and other neurological disorders by the means of recording and stimulation. Despite of the apparent result of these electrical interventions, understanding of the mechanism behind neural stimulation is still inadequate. The use of optical monitoring...

Towards a Microfabricated Flexible Graphene-Based Active Implant for Tissue Monitoring During Optogenetic Spinal Cord Stimulation

Our aim is to develop a smart neural interface with transparent electrodes to allow for electrical monitoring of the site of interest during optogenetic stimulation of the spinal cord. In this work, we present the microfabrication process for the wafer-level development of such a compact, active, transparent and flexible implant. The transparent...

Flexible, graphene-based active implant for spinal cord stimulation In rodents

The most important symptoms of spinal cord injuries (SCIs) are partial or complete loss of sensory and/or motor functions caused by the disruption of the neural pathway between the brain and the extremities of the body. Recent studies have shown that epidural spinal cord stimulation (ESCS) can promote locomotor recovery in patients affected by...
