Abstract
The invention provides systems for handling biofluids including the transport, capture, collection, storage, sensing, and/or evaluation of biofluids released by tissue. Systems of some aspects provide a versatile platform for characterization of a broad range of physical and/or chemical biofluid attributes in real time and over clinically relevant timeframes. Systems of some aspects provide for collection and/or analysis of biofluids from conformal, watertight tissue interfaces over time intervals allowing for quantitative temporal and/or volumetric characterization of biofluid release, such as release rates and release volumes.
Claims18
A device for multiparametric and temporal characterization of sweat comprising:
- a soft and flexible functional substrate for adhering and conforming to a surface of the skin, said functional substrate comprising a microfluidic network channel having a plurality of microchannels and reservoirs configured for time-dependent collection of said sweat;
- and
- a plurality of sensors supported by said functional substrate and configured for multiparametric and temporal analysis of said sweat;
- and
- wherein said microfluidic network channel provides for microfluidic transport of at least a portion of said sweat to said sensors.
