Abstract: A wound therapy system having a wound dressing for treating a wound includes a sensor that measures a pH level at a wound area. The sensor has a circuit that includes a first electrode and one or more second electrodes. The first electrode has a changeable conductivity that changes according to a hydrogen ion concentration level. The one or more second electrodes are configured with a fixed conductivity that does not change with the hydrogen ion concentration level. The first electrode is coated with a porous protective membrane formed from a sulfonated and/or carboxylated copolymer.

Abstract: A microfluidic sensing device, for conducting measures on liquid samples, is disclosed, which includes a housing having: a first opening defining an inlet and/or an outlet for a liquid sample; a detection chamber including a sensor; a first microfluidic path connecting the first opening to the detection chamber, such that the detection chamber can be filled in with the liquid sample; a second opening designed so as to allow the application of a negative and/or positive pressure within the housing; a second microfluidic path connecting the second opening to the detection chamber; a third opening designed so as to allow the application of a negative and/or positive pressure within the housing; a third microfluidic path connecting the third opening to the first microfluidic path; and a waste chamber arranged in the second microfluidic path.

Abstract: Disclosed is a method for liquid measurements including: —providing a sensor including a surface arranged to receive a liquid thereupon, an electrical heating element arranged to heat the surface, and an arrangement for measuring a temperature of the surface; —receiving liquid on the sensor surface; —heating the surface by means of the electrical heating element at a known rate while taking a plurality of temperature measurements thereof in function of time, the heating being at an absolute temperature of at least 90% of the boiling point of the liquid under ambient pressure; and—deriving a volume or a flow rate measurement related to the liquid from the electrical heating rate and the temperature measurements.

Abstract: An ion sensitive system has sets of microfluidic microchannels forming ion sensitive electrodes by the assembly of a substrate with structured microchannels and another substrate including metal contacts on its surface. The integrated ion sensitive sensors are each composed of a microfluidic microchannel to contain an electrolyte, another microfluidic microchannel to contain the analyte and another microfluidic microchannel to contain a membrane liquid that separates the electrolyte from the analyte at the confluent junction of the three solutions. The system has the dimension of a thin and small disc and can be incorporated in an analyzing device.
