To objectively grasp a stress state of a user and to prevent a mental disorder of the user, the following steps are performed: acquiring, via a network, biogas information at multiple timings and time information corresponding to each of the multiple timings, wherein the biogas information represents a concentration of 2-phenoxyethanol of a user acquired by a sensor that detects 2-phenoxyethanol discharged from a skin surface of the user; obtaining reference information representing an upper limit of a normal range of the concentration of 2-phenoxyethanol per unit period of time, using a memory storing the reference information representing the upper limit of the normal range; determining a stress time period during which a concentration of the 2-phenoxyethanol of the user is more than the upper limit of the normal range, based on the acquired biological gas information; and outputting time period information indicating the determined stress time period to an information terminal of the user, to display the stress time period indicated by the time period information on a display of the information terminal.

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 ethylene glycol of the user and is obtained by a sensor that detects ethylene glycol 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 ethylene glycol 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 ethylene glycol 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.

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 phenol of the user and is obtained by a sensor that detects phenol 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 phenol 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 phenol 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.

A method is disclosed comprising providing a biological sample on a swab, directing a spray of charged droplets onto a surface of the swab in order to generate a plurality of analyte ions, and analysing the analyte ions.

An apparatus is disclosed comprising a first device for generating aerosol, smoke or vapour from one or more regions of a target, an inlet conduit to an ion analyser or mass spectrometer, the inlet conduit having an inlet through which the aerosol, smoke or vapour passes, and a Venturi pump arrangement arranged and adapted to direct the aerosol, smoke or vapour towards the inlet.

A vapor sensor comprises a housing with an inlet opening in fluid communication with a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to an output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.

Provided is a biomonitoring device that measures a parameter of a material expelled during use of a toilet by a user. Also provided is a biomonitoring mirror device that identifies a user, detects a febrile illness in a user, dispenses medications/supplements, connects to electrical device accessories in the bathroom, and provides an interactive user interface. Additionally provided is a system for measuring a parameter of a material expelled during use of a toilet by a user. Further provided is a method of determining a physiological parameter of a user.

The present invention provides a device and process that rapidly assesses volatile organic compounds (VOCs) present in a gaseous state by reading gas emitted through a subject's skin into the ambient surroundings. The device delivers rapid high-sensitivity capture, classification and pattern recognition to identify a unique VOC profile derived from that bio-sample. A flexible probe module can be appropriately configured with attachments to collect gases from the air surrounding any person, any area enclosed or proximal to a potential VOC source, and/or in clinical applications, near any skin surface, from zones or areas within or immediate adjacent to a body orifice such as nasal passage, otic canal, mouth, armpit, vagina, urethra, navel, anus, vagina, scalp, torso, palm, foot, etc. The device thus provides a practical screening device for clearing persons of interest, e.g., in a waiting room, planning to enter a room or building, a client seeking a personal meeting, etc., and/or providing a handyman, health care worker, or other service provider, a means of assurance when entering a place of service.

A system is provided for collecting and logging the frequency of flatulence of a person in a selected time period as well as the duration of each occurrence of flatulence. The log entries provide determination of the body cells signaling of the person indicative of the person's health condition whereby underlying diseases may be detected and treated in their early stage.
