This paper reports on the characterization of a microfabricated wafer-scale, graphene-based, soft implant for spinal cord applications. Graphene is used because its high transparency and good conductivity, making it suitable optogenetic Moreover has mechanical strength potentially biocompatible. The consists multi-layered chemical vapor deposited graphene, in form electrodes tracks, encapsulated between 2 layers silicone. Methods such as Raman spectroscopy, optical transmittance, electrical...
Bulk piezoelectric ultrasound transducers on integrated circuits offer unique properties for therapeutic applications of neuromodulation. However, current implementations such are not optimized the high transmit efficiency required to stimulate neurons. This is mainly due challenge implementing a metal layer top film using microfabrication techniques. Here, we propose micromachined capping structure providing an electrical connection with minimal acoustic losses. The can potentially be used...
In the emerging research field of bioelectronic medicine, it has been indicated that neuromodulation vagus nerve (VN) potential to treat various conditions such as epilepsy, depression, and autoimmune diseases. order reduce side effects, well increase effectiveness delivered therapy, sub-fascicle stimulation specificity is required. electrical domain, increasing spatial selectivity can only be achieved using invasive potentially damaging approaches like compressive forces or penetration. To...

2D phased array ultrasonic transducers realized through the combination of bulk piezoelectric ceramics and complementary metal-oxide-semiconductor (CMOS) integrated circuits (IC) are enabling a new range wearable ultrasound therapeutic applications. Traditional have an air backing layer to maximize transmitted acoustic intensity. Yet, pairing silicon substrates commonly used in CMOS is still poorly understood. We lead zirconate titanate (PZT) film on membranes various thicknesses understand...
