  • Publication number: 20240099648
    Abstract: Provided is a system (300) for determining a sweat rate per gland and measuring biomarker concentration. The system comprises an apparatus and a sensor (166). The apparatus receives sweat from the skin and transports the sweat as discrete sweat droplets to the sensor. The sensor senses each of the counted sweat droplets. The system further comprises a processor which counts the number of sensed sweat droplets during a time period. The processor also determines time intervals between consecutive sensed sweat droplets, and receives a measure of the volume of each of the counted sweat droplets. The time intervals and the measure of the volume are then used by the processor to identify sweat burst and rest periods of the sweat gland or glands producing the sweat. This identification process necessarily involves assigning the sweat burst and rest periods to the sweat gland or glands, such that the processor is permitted to determine the number of sweat glands involved in producing the sweat.

  • Publication number: 20240099647
    Abstract: Provided is an apparatus (100) for transporting sweat droplets (112) to a sensor. The apparatus comprises a chamber (102) for filling with sweat. The chamber has an inlet (104) lying adjacent the surface of the skin (106), which inlet permits sweat to enter and fill the chamber. The chamber has an outlet (114) from which a sweat droplet protrudes once the chamber has been filled. The apparatus further comprises a fluid transport assembly which is designed to enable the sweat droplet protruding from the outlet to become detached from the outlet of the chamber. The sweat droplet is subsequently transported by the fluid transport assembly to the sensor. Once the protruding droplet has been released from the outlet, the outlet is made available for a subsequent sweat droplet to protrude therefrom upon further filling of the chamber.

  • Publication number: 20230404729
    Abstract: A wear-out assessment for an oral care system (14) (e.g. an oral cleaning device) is disclosed. A sensor unit (16) of the oral care system is adapted to provide a sensor signal related to a cleaning efficacy of a cleaning function of the oral care system. The sensor unit (16) may be, or may be coupled to, a component which is used during execution of an oral care function of the device, for example a sensor for detecting cleaning progress in the mouth, or a component which drives a cleaning or treatment action in the mouth. The sensor signal (20) is used for performing a wear-out assessment via monitoring characteristics of a signal which is indicative of progress of the oral cleaning efficacy during an operation session (e.g. a clean level in the mouth) and monitoring a length of time that it takes for a certain threshold of efficacy to be reached in a session. If the length of time is over a certain threshold, this can be an indication that the relevant components of the oral care system are wearing out.
