Abstract: The disclosure relates to microchemical (or microfluidic) apparatus as well as related methods for making the same. The methods generally include partial sintering of sintering powder (e.g., binderless or otherwise free-flowing sintering powder) that encloses a fugitive phase material having a shape corresponding to a desired cavity structure in the formed apparatus. Partial sintering removes the fugitive phase and produces a porous compact, which can then be machined if desired and then further fully sintered to form the final apparatus. The process can produce apparatus with small, controllable cavities shaped as desired for various microchemical or microfluidic unit operations, with a generally smooth interior cavity finish, and with materials (e.g., ceramics) able to withstand harsh environments for such unit operations.

Abstract: The disclosed invention provides a biofluid collection device configured with a hexagonal open microfluidic network, which facilitates nanoliter-scale biofluid collection and transport for biosensing applications. In one embodiment, a biofluid sensing device placed on the skin for measuring a characteristic of an analyte in sweat includes one or more biofluid sensors and a hexagonal open microfluidic network biofluid collector. The disclosed collector provides a volume-reduced pathway for sweat biofluid between the one or more sensors and sweat glands when the device is positioned on the skin. In another embodiment, a biofluid collector includes a network of microchannels comprising three or more repeatedly intersecting channels that provide redundant pathways for biofluid transport.
