Zusammenfassung:Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self- righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject). D'une manière générale, l'invention concerne des articles à redressement automatique, tels que des capsules à redressement automatique, destinés à être administrés à un sujet. Dans certains modes de réalisation, l'article à redressement automatique peut être configuré de telle sorte que l'article peut s'orienter par rapport à une surface (par exemple, une surface d'un tissu d'un sujet). Les articles à redressement automatique décrits ici peuvent comprendre une ou plusieurs surfaces de mise en prise de tissu configurées pour venir en prise (par exemple, s'interfacer avec, injecter dans, ancrer) avec une surface (par exemple, une surface d'un tissu d'un sujet). Dans certains modes de réalisation, l'article à redressement automatique peut avoir une forme et/ou une distribution particulière de densité (ou de masse) qui, par exemple, permet le comportement d'auto-redressement de l'article. Dans certains modes de réalisation, l'article à re
