Abstract: Disclosed are devices, systems and methods for epidermal monitoring of a fluid on skin. In some aspects, a device includes an electrochemical sensor comprising two or more electrodes disposed on a first flexible substrate; a microfluidic device comprising a second flexible substrate coupled to the first substrate and structured to include (i) a channel in a first cavity of the second substrate, (ii) one or more holes that connect to the channel and provide one or more inlets, and (iii) a reservoir connected to the channel, in which the electrochemical sensor is aligned with the reservoir; and an adhesion layer coupled to the microfluidic device and attachable to skin, and the device being operable to detect a biomarker in a fluid in secreted by the skin into the microfluidic device.

Abstract: Enclosures for mass delivery of a living biological pest control agent according to the embodiments disclosed herein include a body section having a generally cylindrical wall with opposed ends defining an interior surface, parasitized eggs of a living biological pest control agent (e.g., an endoparasitic insect) adhered to the interior surface of the wall, and at least one egress opening to allow the pest control agent to exit the body section to an exterior environment.
