Improvements in ingestible electronics with the capacity to sense physiologic and pathophysiologic states have transformed the standard of care for patients. Yet despite advances in device development, significant risks associated with solid, non-flexible gastrointestinal transiting systems remain. Here, we disclose an ingestible, flexible piezoelectric device that senses mechanical deformation within the gastric cavity. We demonstrate the capabilities of the sensor in both in vitro and ex vivo simulated gastric models, quantified its key behaviors in the GI tract by using computational modeling, and validated its functionality in awake and ambulating swine. Our piezoelectric devices can safely sense mechanical variations and harvest mechanical energy inside the gastrointestinal tract for diagnosing and treating motility disorders and for monitoring ingestion in bariatric applications.

Systems and Methods for determining a physiological parameter are disclosed. The physiological sensing device can measure a physiological parameter, determine a mood based on the physiological parameter, and render one or more songs associated with the mood.

A portable terminal case having a skin condition-measuring function is disclosed. The case includes a battery case; a bumper case coupled to the battery case; a moisture measurement unit for receiving moisture level information in the skin of a user from a moisture measurement sensor; a contact detection unit for receiving information on the presence or absence of a contact between the bumper case and the skin from a contact detection sensor; an environment measurement unit for receiving surrounding environment information from an environment information measurement sensor; and a control unit for collecting the moisture content and the environment information from the moisture measurement unit and the environment measurement unit.

Systems and methods for analyte monitoring, particularly systems and methods for monitoring and managing life of a battery in an analyte sensor system worn by a user, are provided.

In some embodiments, a wound dressing includes at least one motion sensor for sensing a motion related parameter associated with motion of the wound dressing; and at least one further sensor for sensing a healing related parameter associated with wound healing at a region of tissue of a wound or proximate a wound covered by the wound dressing.

An analyte sensor system is provided. The system includes a base configured to attach to a skin of a host. The base includes an analyte sensor configured to generate a sensor signal indicative of an analyte concentration level of the host, a battery, and a first plurality of contacts. The system includes a sensor electronics module configured to releasably couple to the base. The sensor electronics module includes a second plurality of contacts, each configured to make electrical contact with a respective one of the first plurality of contacts, and a wireless transceiver configured to transmit a wireless signal based at least in part on the sensor signal. The system includes a first sealing member configured to provide a seal around the first and second plurality of contacts within a first cavity. Related analyte sensor systems, analyte sensor base assemblies and methods are also provided.

A wristband biosensing system, a wristband biosensing apparatus, and a biological sensing method are provided. The system includes a wristband body worn on a wrist of a user, at least one physiological signal sensor, at least one deformation sensor, and a processing device coupled to the physiological signal sensor and the deformation sensor. The physiological signal sensor is disposed on the wristband body at a position corresponding to at least one sensing portion of the wrist to detect a physiological signal of each sensing portion. The deformation sensor is disposed around each physiological signal sensor to detect deformation of each sensing portion and output a deformation signal. The processing device receives the physiological signal and the deformation signal, inquires a compensation signal corresponding to the deformation signal, and corrects the physiological signal by using the compensation signal, so as to output a corrected physiological signal of each sensing portion.
