International Classification:

A61B 18/18
H01P 7/08

Abstract:

A system for neuromodulation includes a split-ring resonator (SRR) comprising a resonance circuit, the SRR being implantable in a cranial target site and a source of microwave signals, wherein the microwave signals are deliverable wirelessly to couple with the SRR to produce a localized electrical field, wherein the localized electrical field inhibits one or more neurons at the cranial target site with submillimeter spatial precision.

Abstract:

A tapered fiber optoacoustic emitter includes a nanosecond laser configured to emit laser pulses and an optic fiber. The optic fiber includes a tip configured to guide the laser pulses. The tip has a coating including a diffusion layer and a thermal expansion layer, wherein the diffusion layer includes epoxy and zinc oxide nanoparticles configured to diffuse the light while restricting localized heating. The thermal expansion layer includes carbon nanotubes (CNTs) and Polydimethylsiloxane (PDMS) configured to convert the laser pulses to generate ultrasound. The frequency of the ultrasound is tuned with a thickness of the diffusion layer and a CNT concentration of the expansion layer.
