Abstract: Methods, systems, and devices are disclosed for monitoring the dispensing of a fluid from a container. In one aspect, a system includes a conformal substrate including a mechanically flexible and an electrically insulative material, the substrate attached and conformed to a container containing a fluid; a data acquisition unit including a sensor and a signal processing circuit formed on the conformal substrate, in which the sensor transduces an occurrence of the fluid dispensing from the container into an electrical signal, and the signal processing circuit amplifies the electrical signal; a data processing unit formed on the conformal substrate and in communication with the data acquisition unit to process the amplified electrical signal as data; and a communications unit formed on the conformal substrate and in communication with the data processing unit to wirelessly transmit the processed data to a remote device.

Abstract: Disclosed are flexible and stretchable antenna devices, systems and methods of use and manufacture. In some aspects, a flexible and stretchable antenna device includes an adhesive substrate having flexible and stretchable material properties and capable of adhering to a surface of an object; and an antenna attached on or at least partially embedded within the adhesive substrate, the antenna including a radiating element and a ground element, in which one or both of the radiating element and the ground element include a mesh structure allowing the antenna device to transmit or receive wireless communication signals at a predetermined operating frequency while being stretched.

Abstract: A thin, soft sensor array system that can be deployed over the surfaces of bag bioreactors. The sensor array is fabricated using microfabrication processes along with functionalization methods necessary for measuring pH, glucose, and temperature. Miniature integrated circuit (IC) components are incorporated with the thin-film circuits, allowing for the real-time, on-board data analysis and wireless data communication.
