The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can be used in a variety of different applications, including as components of ingestible identifiers, such as may be found in ingestible event markers, e.g., pharma-informatics enabled pharmaceutical compositions.

This disclosure is directed to devices, systems, and techniques for an external device to receive data collected by an IMD implanted in a patient. The IMD may collect physiological data associated with a patient and store the physiological data in memory. The IMD may determine an amount of the physiological data stored in the memory to send to an external device and send, via a wireless connection, the determined amount of the physiological data stored in memory to the external device.

A device and method for treating a hone includes a bone plate including first and second portions joined to one another via a connecting portion, a rigidity of the connecting portion being less than rigidities of each of the first and second portions in combination with a first sensor mounted on the first portion measuring strain on the first portion and a second sensor mounted on the second portion measuring strain on the second portion.

To enable detection of a plurality of capsule ingestions, the ingestible capsules include a transmitter and processing hardware to generate and transmit the signals. Each ingestible capsule obtains a serial number for distinguishing between the ingestible capsules, and generates a signal indicating that the capsule has been ingested. The signal includes a series of pulses having a particular pulse space and indicating the serial number. Each ingestible capsule transmits the signal to a receiver via the transmitter, where each ingestible capsule is identified based on at least one of: the particular pulse space and the serial number for the ingestible capsule.

Various methods and apparatuses are presented for an ingestible capsule that includes a digital, ingestible sensor component—or ingestible sensor—embedded into the capsule. The ingestible sensor component may be configured to activate upon coming into contact with conductive fluid, such as a body's stomach fluid. Once activated, the ingestible sensor component may be configured to perform various tasks, such as transmitting one or more signals and obtaining biometric data about the body that ingested the capsule.
