A wound dressing according to the present invention comprises at least two impedance reference electrodes, a frame like counter-electrode and stimulation electrodes in a form of an array; and a bioadhesive affinity layer surrounding the stimulation electrodes; said wound dressing being suited for applying on top of the wound so that the stimulation electrode array is on the wound area, and that the at least two impedance reference electrodes and the frame like counter-electrode are suited for placing in contact with the healthy skin surrounding the wound area; which electrodes, are suited for applying LIDC type electrical stimulation current to the wound area and for bioimpedance measurement. The wound dressing according to the present invention provide a continuous, non-invasive and objective solution for monitoring chronic wound healing without disturbing the delicate healing process.

Arrangement for facilitating wound healing, a method for measuring wound healing and a wound dressing

A method for measuring vibration transmittance of a sternum noninvasively includes producing vibration, transmitting the vibration to a first side the sternum through skin and soft tissues, obtaining response data of the sternum from a second side of the sternum through skin and soft tissues, which first and second sides of the sternum are on different sides of the midline of the sternum, and processing said response data for determining transmittance of vibration of the sternum. The response data may be used for defining state of a patient such as sternal instability of the breastbone or abnormal healing in the sternum after open chest surgery by surgeons.

Various embodiments relate to a method, apparatus, system, and a computer program product for suppressing an oscillatory signal Sosc. In the method a composite signal S comprising said Sosc and a modulating signal Smod are provided and the S is high pass filtered to produce estimates of the Sosc and the Smod, wherein the estimate of the Sosc comprises first oscillations during a first state of the modulating signal and second oscillations during a second state of the modulating signal. A first bin associated with said first state and a second bin associated with said second state are defined and assigned for said first oscillation and the second bin for said second oscillation according to a state defined from the estimate of the Smod. A first average waveform for said first oscillations and a second average waveform for said second oscillations are formed and used to suppress the Sosc signal from the composite signal S.

Method for decomposition of a composite signal consisting of oscillatory waveforms and a modulating signal

Method for analyzing the beating of a derived human cardiomyocyte (CM) includes obtaining the derived human CM, capturing a sequence of images depicting the derived human CM over an analysis period, and determining at least one signal descriptive of the beating of the derived human CM during the analysis period on basis of the sequence of captured images. Apparatuses, and a computer program for analyzing the beating of a derived human CM are configured to obtain: the sequence of images depicting the derived human CM over an analysis period, information indicative of the region of the images depicting the derived human CM, information indicative of two or more sub-regions within the region, and determine two or more signals characterizing the displacement within the region of images depicting the derived human cardiomyocyte, each signal characterizing the extent of displacement within a respective sub-region of the region as a function of time.
