UNLABELLED Recently, implantable neural electrodes have been developed for recording and stimulation of the nervous system. However, when the electrode is implanted onto the nerve trunk, the rigid polyimide has a risk of damaging the nerve and can also cause inflammation due to a mechanical mismatch between the stiff polyimide and the soft biological(More)
Peripheral nerve cuff electrodes with roughened Pt black (BPt) are coated with polyethylene glycol (PEG) and Nafion (NF). Although the influence of coated PEG and Nafion on roughened BPt on the electrical properties is weak, the cuff electrode with BPt/PEG and BPt/Nafion exhibits some very important properties. For example, it markedly decreases interfacial(More)
Polyimide (PI)-based electrodes have been widely used as flexible biosensors in implantable device applications for recording biological signals. However, the long-term quality of neural signals obtained from PI-based nerve electrodes tends to decrease due to nerve damage by neural tissue compression, mechanical mismatch, and insufficient fluid exchange(More)
Nerve cuff electrodes for peripheral nerve prostheses are required chronically implanted electrodes which simultaneously stimulate and record nerve activity. It is inevitable challenge to investigate electrode material with low interfacial impedance and enhanced charge transfer capacity. In this study, stimulus nerve cuff electrodes on polyimide with Pt,(More)
We newly fabricated and characterized the double layered nanoporous Pt (NPt) thin film on silicon substrate for enzyme-free glucose sensing applications. The surface morphologies of the fabricated NPt film were characterized using field emission scanning electron microscopy (FESEM). The fabricated NPt films exhibited highly dense nanopores with irregularly(More)
