  • Publication number: 20240090126
    Abstract: A novel methodology of forming a three-dimensional electronic device according to various embodiments of the present invention is described. The methodology comprises, at least, a step of laser folding, using only a laser, a two-dimensional electrically insulating printed circuit board at least partially covered with at least one metal layer, with the laser impinging upon the at least one metal layer to make one or more folds of the printed circuit board to form a three-dimensional electronic device structure.

  • Publication number: 20240000346
    Abstract: Various examples are provided related to interstitial fluid (ISF) or extracellular fluid (ECF) harvesting and processing. In one example, a microfluidic monitoring platform includes a microneedle patch including microneedles on a first side; an osmotic patch on a second side of the microneedle patch that includes glycerogel or hydrogel equilibrated with glycerin or glucose; and a microfluidic or fluid transport film or material channel between the osmotic patch and the microneedle patch. The channel can extract fluid from the osmotic-microneedle patch complex. In another example, a wearable electrochemical sensing system includes a monitoring platform including a microneedle-osmotic patch, a microfluidic or fluid transport film or material channel, and at least one sensor between the channel; and processing circuitry coupled to the at least one sensor. The processing circuitry can monitor presence of a chemical or biomarker in the fluid based upon signals obtained from the sensor.

  • Publication number: 20220298378
    Abstract: Systems and methods relate to applying a coating to a substrate. Coatings can be generated using layer-by-layer application techniques. Typically, application of a first aqueous solution is alternated with application of a second aqueous solution. Example first aqueous solutions include polyethyleneimine (PEI) and hydroxy-terminated poly(dimethylsiloxane) (PDMS-OH). Example second aqueous solutions include silicate and PDMS-OH. In some instances, first aqueous solutions and/or second aqueous solutions additionally include methyl-terminated PDMS (PDMS-CH3).

  • Publication number: 20200163656
    Abstract: Microfluidic devices are provided for continuous sampling of biological fluid for extended periods of time, e.g. for periods of time up to and including 10 days. The microfluidic devices can be made from porous hydrophilic substrate, e.g. hydrophilic paper substrates. The devices can include a collection pad, an evaporative pump, and a channel connecting the collection pad and the evaporative pump. Hydrogels at the collection pad can promote collection of sweat or other biological fluids from a subject, which in some aspects is assisted by the use of one or more microneedles on the substrate. An evaporative pump can provide for long periods of sampling by providing continual pumping, e.g. through the use of an evaporation pad where sampled fluid can evaporate.
