Abstract: Microfluidic devices for sterilizing fluids using pulsed electric fields are disclosed. In some embodiments, a device may include first and second electrode layers and a spacer layer positioned between the electrode layers. The spacer layer may define one or more fluid channels extending between the electrode layers. A power supply may be coupled to the electrode layers and configured to supply voltage pulses to the electrode layers to generate electric field pulses within the fluid channels. In some embodiments, the electrode layers may be textured such that the electric fields generated in the fluid channels are non-uniform.

Abstract: Triboelectric nanogenerators are provided that are textile-based, combine embroidery, silanizing agents, highly networked conductive nanoparticles, and a conformable electronegative layer, and can produce a stable energy source with high power density. Electronic textiles are also provided that utilize such triboelectric nanogenerators to convert the biomechanical energy of a wearer into electrostatic energy that can power electronic devices coupled with the triboelectric nanogenerator. Methods of manufacturing the triboelectric nanogenerators and related electronic textiles are also provided.

Abstract: The device of the present disclosure is configured for laparoscopic use, particularly to insert a fastener into a plate at an angle of up to 180° from the plane of insertion. The device is further configured to carry a plurality of fasteners, a tightening tool, a cutting device, and tweezers simultaneously to facilitate a rapid procedure while lessening the chance of infection by limiting the amount of times the device must be removed and re-inserted.

Abstract: A photodetector is provided that includes a FET structure with a channel structure having one or more nanowire structures. Noble metal nanoparticles are positioned on the channel structure so as to produce a functionalized channel structure. The functionalized channel structure exhibits pronounced surface plasmon resonance (SPR) absorption near the SPR frequency of the noble metal nanoparticles.
