A piezoelectric film sensor (3) of a swallowing sensor (1) includes a plurality of sensing portions (3A) and (3B) in a longitudinal direction of the neck region. The piezoelectric film sensor (3) is located within a range of movement of thyroid cartilage (103), which occurs along with swallowing, and is attached to skin of an anterior neck region (102). The piezoelectric film sensor (3) individually outputs analog signals (S1a) and (S2a) along with deformation of the plurality of sensing portions (3A) and (3B). The swallowing sensor (1) includes pre-processing units (21) and (22) and a signal processing unit (23). Each of the pre-processing units (21) and (22) separates the analog signal (S1a) or (S2a) into a displacement signal that is a low frequency component and a sound signal that is a high frequency component. The signal processing unit (23) determines whether the swallowing occurs based on the displacement signal.

Novel tools and techniques are provided for the detection and differentiation of activities and/or conditions based on measured bio-signals.

This invention is a system for nutritional monitoring and management which includes a camera, a spectroscopic sensor, a fiducial component, a wearable biometric sensor, a smart utensil or dish, a passive feedback mechanism which provides a person with information concerning food item types and/or quantities, and an active stimulus mechanism which modifies the person's food-related physiological processes. This system can help a person to improve their dietary habits and health.

A system for monitoring infant feeding habit includes a nipple having an embedded pressure sensing passage and pressure sensing opening. The pressure sensing opening is proximate the nipple feeding opening. The pressure sensing passage allows monitoring of change in pressure of infant sucks and swallows throughout feeding.

An oral care device for placement in the oral cavity. The oral care device may include a support component, a piezoelectric component, and/or sensor and/or a therapeutic element. The support component is configured for placement between one or more maxillary teeth and one or more mandibular teeth. The piezoelectric element is configured to generate electrical energy from relative movement of the maxillary teeth and the mandibular teeth. The sensor is configured to sense a condition in the oral cavity. The therapeutic element is configured to release a therapeutic into the oral cavity. The device may include any one or any combination of the piezoelectric component, the therapeutic element, and the sensor.

A manometric catheter probe includes a flexible printed circuit, one or more pressure sensor assemblies coupled to the flexible printed circuit along a length of the flexible printed circuit, and a first flexible sleeve. Each pressure sensor assembly includes a body. The body includes a central cavity configured to receive the flexible printed circuit and an annular recess of the body. Each pressure sensor assembly further includes a microelectromechanical systems (MEMS) sensor disposed in the annular recess, an electrical connector configured to electrically couple the MEMS sensor and the flexible printed circuit, and a first flexible sleeve disposed over the annular recess of the body. The first flexible sleeve includes a fluid configured to communicate pressure to the MEMS sensor, and a second sleeve is disposed over the pressure sensor assembly.

Various embodiments include methods and electronic devices for tracking hydration of a user. Embodiments may include determining an amount of liquid consumed by the user based on a predetermined baseline consumption rate for the user and a number of sips or swallows detected by a sensor, and reporting an indication of a determined hydration level of the user based on the determined amount of liquid consumed. Some embodiments include determining the user's predetermined baseline consumption rate based on previously counted sips or swallows, either detected by the sensor or input by the user, while the user consumed a known amount of liquid. Some embodiments include selecting the predetermined baseline consumption rate for the user based on the determined type of liquid being consumed. Some embodiments include determining the hydration level of the user further based on a context in the user is drinking and/or the type of liquid being consumed.

A tool for evaluating, diagnosing, and treating oral motor dysfunction in subjects such as infants.

A method of assisting a manometry procedure includes recording, by a processor, a plurality of pressure measurements taken by a catheter inserted within a gastrointestinal tract of a patient, determining, by the processor, a pressure pattern based on the plurality of pressure measurements, and determining whether the determined pressure pattern is an acceptable pressure pattern or an unacceptable pressure pattern.

A swallowing medical device includes: an attachment unit configured to be attached to a target portion of a human body for a medical operation; a control unit configured to control the medical operation; and a storage configured to store use information regarding a use state over time of the attachment unit. The control unit executes a control for restricting use of the attachment unit on the basis of a fact that the use information does not satisfy a set condition for ensuring a characteristic of the attachment unit.
