Disclosed here are methods and systems for assessing an emotional response of a subject or a group to a sensory stimulus. The methods employ models that infer emotional response based on individual traits of subjects or groups.

A method comprising: acquiring via a network biogas information representing a concentration of furfural of the user acquired by a sensor that detects the furfural discharged from a skin surface of the user; obtaining the reference information representing a lower limit of a normal range of the concentration of furfural per unit period of time, using a memory storing the reference information; and outputting information related to stress of the user an information terminal of the user, after it is determined that a frequency that concentration of the furfural of the user per the unit period of time is less than the lower limit of the normal range tends to increase, based on the biogas information acquired in a pregnancy period of the user.

In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of heptadecane of the user and is obtained by a sensor that detects heptadecane released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of heptadecane per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of heptadecane of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

The subject invention provides sensor systems that can detect biomarkers related to wound healing (e.g., uric acid, adenosine, arginine and/or xanthine). In one embodiment, the subject invention pertains to materials and methods for monitoring biomarkers non-invasively in a wound and a biofluid (e.g., sweat) in the proximity of the wound, optionally, including other physiological fluids. Skin based, non-invasive enzymatic electrochemical biosensor on a wearable platform (e.g., sweat patch) that can evaluate the healing of wounds through assessment of its biomarker levels are provided. This non-invasive detection from physiologically biofluids can reduce or eliminate occlusion effects.

Disclosed herein is a system and a method for generating stress level information for an individual and stress level resilience information for an individual, which includes a stress information processing module configured to process stress information for the individual, the stress information for the individual comprising at least two of psychometric information for the individual, physiological information for the individual, behavioural information for the individual, and cognitive function information for the individual

Typical electrochemical sensors measure target-induced changes in current output. Such measures of target binding are inconsistent across individual sensors, and furthermore, signal will drift over time when the sensor is deployed for long periods. These shortcomings can be avoided by the novel use of chronoamperometry to measure current decay kinetics as the indicator of target binding. Current decay lifetimes will vary in a concentration dependent manner, but remain stable across individual sensors and over time, allowing for calibration-free operation. By these methods, aptamer based electrochemical sensors and other sensor types may be deployed in vivo for extended periods of time and will provide accurate measurement of target binding without calibration.

A cover for use with a measuring device body that includes a sensor portion having a distal end with a sensor having a measurement surface and a proximal end opposite the distal end, and a grip connected to the proximal end of the sensor portion. The cover includes a cover member configured to cover the measurement surface of the sensor, and a support member at least on a side of the sensor portion opposite to the measurement surface, and the support member is connected to the cover member.

A cover for covering an oral device that includes a first sheet member made of a first resin, and a second sheet member made of a second resin and facing the first sheet member, wherein when a first direction is a direction along a surface of the first sheet member and a second direction is a direction along the surface of the first sheet member and orthogonal to the first direction, the first sheet member and the second sheet member are joined to each other in a bag shape so as to define an opening at a first side in the first direction. A protruding portion protrudes from the second sheet member and past an outer edge of the first sheet member at the opening in the first direction.

A device for treatment and collection of saliva provides a base containing aa suction source. A tip having an inlet for collecting a saliva sample is removably attached to the base. A filter material, selected to allow passage of a target biomarker in the saliva sample, is disposed within the tip on a fluid path from the inlet. A collection chamber is disposed on the fluid path downstream of the filter material. The suction source is in fluid communication with the fluid path to draw saliva into the inlet of the tip, through the filter material, and to the collection chamber. Methods for collection of a saliva sample are also provided.

A circuit housing (100) for a wearable intraoral application, including an inner layer (105-1) of a first material (101-1) for waterproof enclosure of an electronic circuit (103); and an outer layer (105-2) of a second material (101-2) for spatially fitting the circuit housing to a set of teeth (111), at least partially covering the first material (101-1).
