Abstract: The present disclosure discloses an arrangement for measuring a biosignal. The arrangement has a sensor module and a control module. The sensor module has structure for sensing at least one biosignal and a first connector for interfacing with the control module. The control module has a first counterpart connector connected to the first connector of the sensor module, structure for processing biosignal data sensed with the sensor module, a storage memory for storing processed bio signal data, a rechargeable battery for providing operating power for the control module, structure for wirelessly transmitting the processed biosignal data to a computing device, such as a PC, a tablet PC or a smart phone, for post-processing, and a second connector for interfacing with a second electrode.

Abstract: The present invention relates to sensory for measuring signals on the surface of the skin and for producing sensory. In the sensory in accordance with the invention, the electrode surfaces required for measuring of a signal and/or conductors required for transmitting of a signal have been fastened to the textile material of an outfit or accessory used on the body. In the method in accordance with the invention, the electrode surfaces required for the sensory and/or conductors are added to the textile material of an outfit or accessory used on the body.

Abstract: The present invention relates to a method for recognizing and measuring heartbeat in physical training, in which method individual heartbeats are recognized and measured from the electrical signal of the heart, the EKG signal, on the area of waist and/or on the body area below the waist by means of two or more electrodes (2, 3) integrated to an outfit (1) or to a part of an outfit, and/or by means of two or more electrodes integrated to one or several wearable sensors, and for calculating various quantities describing the function of the heart. In the method in accordance with the invention, for recognizing and measuring heartbeat, the signals received from the heart are processed and examined with two or more different ways for improving the reliability of calculation and for decreasing the impact of noises.

Abstract: The present invention relates to a method and an outfit for measuring of action of muscles of body, in which method electrical signals created by active muscles are measured with a measuring device and a response from action of muscles is given with a response device with a signal perceptible to a user. In the method in accordance with the invention electrical signals of muscles at various points of the body and/or limbs are measured with one or more measuring devices attached and connected to one or more outfits, the functioning of various muscles is monitored and the information is processed in measuring devices. In the outfit in accordance with the invention there are one or more measuring devices integrated for measuring the electrical signals created by the muscles, for monitoring the action, for processing the information, and the outfit includes a response device for giving response.

Abstract: The object of the invention is a method for determination of endurance and sensitivity to fatigue of a muscle. In this method one or more recording electrodes are placed on top of the muscles to be tested from the test subject and the action potentials of the muscle cell membrane of a muscle are measured by recording electrodes and equipments. It is difficult to define the endurance and sensitivity to fatigue of a person's muscles in comparison with the general population. In the method according to the invention a frequency analysis, the so-called FFT-analysis, is performed to the recorded EMG-signal, and by using this analysis with three or more calculation parameters the lowering of the conduction rate of a muscle cell membrane is observed as well as the rate of change of the calculation parameters as a function of time, and a comparable value is obtained which indicates the endurance and sensitivity to fatigue of a muscle.
