1. A device, comprising:
- a reversibly responsive expandable device housing configured to reversibly expand or contract and primarily reside in the stomach of a subject;
at least one member motor;
at least one actuatable mechanical member operably coupled to each of the at least one member motor and the housing; and
at least one crystalline colloidal array sensor operably coupled to the at least one member motor and configured to detect at least one chemical in the stomach of the subject.

Abstract
Embodiments disclosed herein relate to methods, devices, and computer systems thereof for reducing stomach volume in a subject. In certain embodiments, a subject receives a stomach-volume-reducing device that optionally includes at least one reservoir configured to release at least one appetite suppressant. In an embodiment, the stomach-volume-reducing device is responsive to one or more environmental conditions of the subject, for example, pH or chemical chemicals in the stomach of the subject. In an embodiment, the stomach-volume-reducing device controls hunger in the subject.
