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.

Unobtrusive wireless electronic systems for monitoring and facilitating patient compliance

Disclosed are methods for fabrication of flexible circuits and electronic devices in cost effective manner that can include integration of submicron structures directly onto target substrates compatible with industrial microfabrication techniques. In one aspect, a method to fabricate an electronic device, includes depositing an electrically conductive layer on a processing substrate including a weakly-adhesive interface layer on a support substrate; depositing an insulating layer on the conductive layer to attach to the conductive layer; forming a circuit on the processing substrate by etching selected portions of the conductive layer based on a circuit design; and producing a flexible electronic device by attaching a flexible substrate to the formed circuit on the processing substrate and detaching the circuit and the flexible substrate from the interface layer, in which the flexible electronic device includes the circuit attached to the flexible substrate.
