Abstract: The invention relates to silk electronic components and methods for fabricating the same. The silk electronic components can be used as novel devices, such as implantable bioelectric and/or biophotonic devices, biosensors, surveillance devices, invisible cloaks, electromagnetic concentrators or antennas.

Abstract: Provided herein are silk fibroin-based photothermal elements and uses thereof. The silk fibroin-based photothermal elements comprise a plurality of plasmonic nanoparticle distributed in a silk fibroin matrix, and can generate heat when the plasmonic nanoparticles are exposed to electromagnetic radiation. The silk fibroin-based photothermal elements can be adapted to be conformable and biodegradable, and can further be integrated with various electronic components, such as a thermo-electric device for conversion of heat into electricity. The invention is useful for various in vivo applications, such as photothermal therapy, controlled drug-delivery devices or wireless powering of implanted micro-devices.

Abstract: An apparatus and method are disclosed for detecting terahertz radiation at room temperature. A detecting pixel includes a sub-wavelength split-ring resonator, and is mechanically coupled to (but thermally decoupled from) a substrate via a cantilever formed from two materials that have a significant mismatch in their thermal expansion coefficients. Incident radiation causes the split-ring resonator to resonate, thereby generating heat that is transferred to the cantilever, causing the cantilever to flex. An optical readout system includes a secondary light source, such as a laser, that shines on a reflective surface on the pixel, whereby a photodiode detects the reflected light and permits calculation of a relative deflection of the pixel in the nanometer range. An exemplary detector has a noise equivalent power rating of approximately 60 pW/?Hz.
