An on-body wearable bio-fluid collection and sensing device including an interface or interface surface comprising at least one biocompatible material for contacting a bodily part; at least one inlet for receiving the bio-fluid, at least one outlet for evacuating the bio-fluid, a plurality of semiconductor sensors configured to analyze the received bio-fluid, at least one reference electrode for biasing a bio-fluid gate of at least one of the semiconductor sensors, and at least one micro-fluidic or nano-fluidic channel in fluid communication with the at least one inlet, the at least one outlet and the at least one reference electrode; the at least one micro-fluidic or nano-fluidic channel includes the plurality of semiconductor sensors.

Bio-fluid collection and sensing device, system and method

Presented herein are devices for collecting and/or channeling a biofluid (e.g., sweat, tears, saliva) and detecting and/or quantifying one or more biomarkers in the biofluid. The one or more biomarkers may include, for example, ions, salts thereof, hormones and/or steroids, proteins, metabolites and organic compounds. In certain embodiments, the devices described herein include a specially designed interface and a zero-energy micro pump that allow the device to be comfortably affixed directly to the skin of a user while biofluid is efficiently and non-invasively collected from the skin of the user. In certain embodiments, the biofluid collection and sensing device is housed on or in another wearable device, such as a wrist band or a smart watch. In certain embodiments, the devices described herein are disposable (e.g., after a certain period of use and/or wear the device can be disposed and replaced with a low-cost replacement).
