Abstract: Embodiments disclosed herein relate to an ingestible electronic device configured to provide short term electrical stimulation to a stomach of a subject. The device may include a non-expandable housing and two or more electrodes disposed on the non-expandable housing to apply the short term electrical stimulation to the stomach of the subject. In some instances, the short term electrical stimulation may be on the order of 1 hour or less. In some instances, the ingestible electronic device may utilize the natural gastrointestinal processes of the subject to retain the ingestible electronic device for an appropriate time period within the stomach. For example, the subject may first ingest the ingestible electronic device and the device may travel into the stomach of the subject. The device may then apply electrical stimulation to the stomach for an appropriate time period prior to passing out of the stomach via a pyloric orifice of the stomach.
