1. A system for acquiring at least one sample from a fluid, the system comprising:
- one or more devices;
each device including a sampling mechanism having;
an isolated cavity that is initially inaccessible to the external fluid;
an electrically passive timing mechanism including a piercing structure; and
a mechanical structure separating the isolated cavity from the exterior environment, wherein at the end of a timing interval the piercing structure of the timing mechanism pierces the mechanical structure, bringing the isolated cavity in contact with the external fluid.

Abstract
An electrically passive device and method for in-situ acoustic emission, and/or releasing, sampling and/or measuring of a fluid or various material(s) is provided. The device may provide a robust timing mechanism to release, sample and/or perform measurements on a predefined schedule, and, in various embodiments, emits an acoustic signal sequence(s) that may be used for triangulation of the device position within, for example, a hydrocarbon reservoir or a living body.
