The number of implantable bidirectional neural interfaces available for neuroscientific research applications is still limited, despite the rapidly increasing number of customized components. We previously reported on how to translate available components into ”ready-to-use” wireless implantable systems utilizing components off-the-shelf (COTS). Th...
The variety of "`ready-to-use'" implantable recording and stimulation systems commercially available for neuroscience is very limited and fabrication of custom made implants is commonly considered expensive and time consuming. We present a circuit design that allows cost efficient and fast translation of available components into fully wireless imp...
Wireless implants for interaction with the cortex have developed rapidly over the last decade and increasingly meet demands of clinical brain–computer interfaces. For such applications, well-established technologies are available, suitable for recording of neural activity at different spatial scales and adequate for modulating brain activity by cor...
Wireless powering allows the implementation of active implanted medical devices (AIMD) without batteries being inserted. The power is commonly transferred by an inductive link, which exhibits a strong relation between efficiency and coil configuration. For example, the electro-magnetic coupling and consequently the transferable power rapidly decrea...
Thin-film-based electrodes used to interact with nervous tissue often fail quickly if used for electrical stimulation, impairing their translation into long-term clinical applications. We initiated investigations about the mechanical load on thin-film electrodes caused by the fact of electrical stimulation. Platinum electrodes of Ø 300μm on a polyi...
In case of a neuro-degenerative disorder, closed-loop brain stimulation is able to reduce tremor, rigidity, bradykinesia, as well as postural instability and consequently to improve the patient's quality of life. Therefore, we investigate a human machine interface based on a multi-implant approach, which avoids drawbacks of conventional systems. Th...
