Provided is a system for correcting a sweat analyte measurement for temperature. The system comprises a sweat collector () for collecting sweat from skin (). The collected sweat is drawn from the sweat collector to an outlet () via a capillary (). The sweat is drawn through the capillary by capillary action and evaporation of the sweat from the outlet. The evaporation of the sweat from the outlet depends on the temperature. A flow sensor () measures a flow rate of the sweat being drawn through the capillary. An analyte sensor () obtains the sweat analyte measurement. The system further comprises a controller which is configured to determine a temperature from the measured flow rate. The sweat analyte measurement is then corrected using the determined temperature. Further provided is a method for correcting a temperature-dependent sweat analyte measurement.

A sweat sensing system comprises a mesh for location over a sweat surface on which sweat is formed or collected, and a vibration system for vibrating the mesh to nebulize sweat droplets. The nebulized sweat droplets are condensed on a sensing surface, and a sweat sensor performs biomarker sensing of the sweat at the sensing surface.

Sweat sensing system

A system for predicting the onset of a physiological condition of a subject combines an in-vitro subject model having input parameters relating to actual or predicted external stimuli to which the subject is or may be exposed and an in-silico model. The in-vitro model outputs subject-specific parameters which are not being monitored, or cannot be monitored, in-vivo. The in-silico subject model uses subject-specific parameters to predict the response of the subject to the actual or predicted external stimuli and thereby predict an onset of a physiological condition of the subject.

Provided is a method of determining a concentration (C) of a first analyte (a) in sweat excreted by a first sweat gland type at a first skin location (i) having the first sweat gland type and a second sweat gland type. The method comprises measuring a first concentration (I) of the first analyte in sweat excreted at the first skin location and measuring at least one parameter of sweat excreted by the second sweat gland type at a second skin location (ii) having the second sweat gland type but not the first sweat gland type. The at least one parameter is used to determine a dilution factor (II) which quantifies dilution of the first analyte by sweat excreted by the second sweat gland type at the first skin location. This dilution factor (II) is then used to correct the first concentration (I) so as to determine the concentration (C). Further provided is an apparatus () for determining the concentration (C).

Method and apparatus for differential sweat measurement

A biological cell preservation or culturing arrangement () comprises a chamber defining a fluid retaining space () for retaining in use a body of fluid () and a deformable membrane () in communication with the fluid retaining space, and being manipulable by an electroactive polymer actuator arrangement () to undergo a defined topology change to induce in the fluid a pattern of fluid flow by which fluid is exchanged between a sub-region () immediately proximal the deformable membrane and a sub-region () removed from the deformable membrane.

Cell preservation or culturing arrangement

An actuator device has a temperature sensing means and a controller adapted to apply a high frequency AC signal to stimulate internal self-heating to thereby maintain a temperature of an actuator member of the device at a certain fixed temperature, this temperature being elevated with respect to an initial temperature of the actuator member. This ensures that thermal drift may be mitigated or eliminated by compensating for any changes in environmental temperature through raising or lowering the level of the heating signal.

The present application relates to a cold plasma device () for treating skin (). The cold plasma device () comprises a cold plasma generator () adapted to generate cold plasma that produces reactive species for treating said skin (), and a manipulator () adapted to manipulate said skin () to increase exposure of bacteria on said skin to said reactive species during use of the device.

A flow control device comprises a laminate structure of an electroactive material layer and a non-actuatable layer. An array of orifices is formed in one of the layers wherein the orifices are open in one of the rest state and actuated state and the orifices are closed in the other of the rest state and actuated state. Actuation of the electroactive material layer causes orifices to open and close so that flow control function may be implemented.

The invention relates generally to electroactive material actuators (and combined sensor-actuators) having embedded magnetic particles () for facilitating enhanced actuation and/or sensing effects.

Actuator device and method

An actuator device () comprises an electroactive polymer (EAP) and a driver () for generating a electrical drive signals which give opposite polarity voltages and thus electrical field within the electroactive polymer at different times. In this way, charge build-up can be reduced or avoided, while prolonged activation times are still possible. This improves the performance and/or lifetime of the device.

Actuator device based on an electroactive polymer

An actuator or sensor device comprises an electroactive polymer (EAP) arrangement which extends between fixed opposite ends. The electroactive polymer arrangement comprises a passive carrier layer and an active electroactive polymer layer, wherein at or adjacent the ends, the passive carrier layer and the active EAP layer are mounted with one over the other in a first order, and at a middle area between the ends, the carrier layer and the active EAP layer are mounted in an opposite order. This enables internal stresses and moments within the electroactive polymer arrangement to be used more effectively to contribute to displacement or actuation force.

The invention provides a surface analysis device for application to a receiving surface to enable analysis of at least one measure of an elasticity of said surface across multiple different linear stretches or sections of the surface. The device includes a two-dimensional arrangement of actuators and sensors, comprising at least one actuating element, at least one sensing element, and at least one further sensing or actuating element. Selected sets of two or more of these elements are activated together by a controller, each set including at least one actuator and one sensor, to thereby obtain a measure of elasticity between each actuator and sensor pair in the set. Elasticity measures are obtained based on stimulating a deformation in the receiving surface at the actuator site, and measuring a resultant pressure and/or force exerted by the receiving surface at a further displaced point. Sensors may monitor a change in the exerted pressure and/or force for example.
