Abstract: Some aspects of the present disclosure are related to articles for measuring electrical signals internal to a subject, e.g., of the gastrointestinal tract (GI tract). The articles, in some embodiments, are ingestible and/or implantable. In some embodiments, the articles comprise a substrate comprising a plurality of electrodes, the substrate having a Young's elastic modulus of greater than or equal to 0.01 MPa and less than or equal to 200 MPa. In some such cases, the Young's elastic modulus of the substrate facilitates elastic recoil of the substrate such that at least a portion of the plurality of electrodes contact a surface of a tissue at the location internal to the subject (e.g., the GI tract) and thus facilitate measurement of electrical signals at the location internal to the subject. Other aspects are related to methods of using the articles, for example, to monitor electrical signals from the location internal to the subject.

Abstract: A drug delivery device for administration to a subject is provided. In some embodiments, the drug delivery device includes a reservoir containing an active pharmaceutical ingredient and a potential energy source. The drug delivery device also includes a trigger operatively associated with the potential energy source, where the trigger is configured to actuate at a predetermined location within the subject. The drug delivery device also includes a rupturable membrane disposed along a flow path extending between the reservoir and an outlet, where the membrane is configured to rupture when the trigger is actuated. Once the trigger is actuated, the potential energy from the potential energy source may be released to expel the active pharmaceutical ingredient in a jet through the outlet.

Abstract: A drug delivery device may be configured to delivery an active pharmaceutical ingredient (API) to a subject via the subject's oral-gastrointestinal (GI) tract. The drug delivery device may be configured to deliver a payload of an API while within the GI tract of the subject. The drug delivery device may include a reservoir, a potential energy source, a plurality of outlets, and a plurality of valves, wherein each outlet has a corresponding valve. The drug delivery device may further include a sensor configured to sense the direction of gravity, and the valves may be selectively opened based on a sensed direction of gravity. Thus, the drug delivery device may dispense a dose of API within the GI tracts of the subject based at least in part on the sensed direction of gravity.

Abstract: An all-in-one insulin pen includes a handheld housing that houses a glucose testing module, an insulin delivery module, a wireless communication module, and a microcontroller. The glucose testing module tests a one-time glucose concentration of a patient. The insulin delivery module automatically administers an insulin bolus to the patient based at least in part on the one-time glucose concentration.
