Abstract: A printer is configured for printing with conductive ink for applying a conductive pattern to a surface including a wheeling structure for moving the printer over the surface and a transfer unit for applying a layer of electrically conductive ink to the surface. To provide accurate printing with the ability to obtain fine tolerances, the transfer unit has a printing drum rotatable about a printing drum axis and defining a printing drum periphery moving between a first zone and a second zone by rotation of the printing drum. The printing drum periphery, in the first zone, receives the conductive ink and in the second zone transfers the ink to the surface.

Abstract: A shielding barrier (32) is carried by one or more electrodes (22) of a cleaning and/or treatment unit (12) for an oral care device, and arranged for interposing contact of an exposed conductive portion (25) of the electrodes (22) by other components or external objects.

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.

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.

Another aspect provides an apparatus for carrying out this method.

Abstract: A device (1) for determining sweat parameters of a user is provided, which device comprises a microfluidic structure (10) having a collection chamber (16) configured to collect sweat from a first skin area (i), and a sensor (12) configured to determine a sweat parameter from sweat from the first skin area (i).

A method for determining sweat parameters of a user is also provided.
