Abstract: Described embodiments include a system, method, and apparatus. A system includes an extracellular-fluid collection device configured to be positioned at a location on a skin of a mammal. In an embodiment, the mammal includes a live human. The system includes an ultrasonic wave transmitter configured to emit ultrasonic shear waves directable at the location. The ultrasonic shear waves have a frequency or amplitude selected to increase a permeability of the skin of the mammal to an extracellular-fluid. In an embodiment, the system includes a sensor configured to determine a rate or amount of extracellular-fluid collected by the extracellular-fluid collection device. In an embodiment, the system includes a fluid collection controller configured to regulate a parameter of ultrasonic shear waves transmitted by the ultrasonic wave transmitter in response to a determined rate or amount of fluid collected by the extracellular-fluid collection device.

Abstract: An embodiment simultaneously receives light waves emanating from an object and having first frequency components f1.1 and f1.2, and pumped monochromatic coherent light waves having a second frequency f2. The method non-linearly combines the light waves having the first frequency component f1.1 and the pumped monochromatic coherent light waves, and generates coherent light waves having a third frequency component f3.1 that is a sum of the first frequency f1.1 and the second frequency f2. The method non-linearly combines the light waves having the first frequency component f1.2 and the pumped monochromatic coherent light waves, and generates coherent light waves having a third frequency component f3.2 that is a sum of the first frequency f1.2 and the second frequency f2. The method digitizes the generated coherent light waves and outputs an image responsive to the light waves emanating from the object.

Abstract: Embodiments include an apparatus and method. An apparatus includes a metasurface that coherently upconverts light waves having a first frequency f1. A substrate forms a first plasmonic surface. A plasmonic nanoparticle forms a second plasmonic surface. A layer of a second-order nonlinear dielectric material is disposed between the first plasmonic surface and the second plasmonic surface. The metasurface has at least three plasmonic resonant modes including a first plasmonic resonant mode having a first frequency f1, a second plasmonic resonant mode having a second frequency f2, and a third plasmonic resonant mode having a third frequency f3 that is a sum of the first frequency f1 and the second frequency f2. The apparatus includes a second light propagation path from a source of pumped monochromatic coherent light waves having the second frequency f2 to the metasurface. A digital image capture device captures the generated light waves having the frequency f3.

The system includes an ultrasonic wave transmitter configured to emit ultrasonic shear waves directable at the location. The ultrasonic shear waves have a frequency or amplitude selected to increase a permeability of the skin of the mammal to a medicament released by the medicament-eluting device. In an embodiment, the system includes a structure carrying the medicament-eluting device and the ultrasonic wave transmitter. In an embodiment, the system includes a cavitation sensor configured to detect a cavitation event in the mammal. In an embodiment, the system includes a cavitation controller configured to limit a power of the ultrasonic shear waves directed at the location to a level below a cavitation threshold of the mammal.
