Problems solved by technology

[0005] A disadvantage of this known monitoring device is its instability, since in order to obtain a good heart rate measurement, the pressure sensor needs to be positioned precisely adjacent to the blood vessel from which the measurement is to be obtained
Therefore, the device is not intended for use by athletes who prefer to use the device while running, jumping and / or in any other way

Embodiment Construction

[0024] FIG. 1 shows a hand 1 and a wrist 2 of a human arm 3 using a first embodiment of a monitoring device 4 . Referring to FIG. 2 , the device 4 comprises a housing 6 having a time display 8 with two hands 10 and 12 and a watch strap having a first strap part 14 and a second strap part 16 . The device is configured to provide a capacitor 22 having electrodes 18,20. Each of the strap portions 14, 16 is provided with a capacitor electrode 18, 20 in the form of a plate 18, 20 which together form a capacitor 22 during use when the device is worn by a user. Capacitor plates may be positioned adjacent to different surface portions. In the illustrated embodiment, in use, the surface portions are located on substantially opposite sides of the arms 3, ie on sides of the arms 3 which are substantially facing away from each other.

[0025] Electrodes 18 and 20 are electrically coupled to oscillator 24 which, in operation, sends a periodic electrical signal through capacitor 22 . Th...

Abstract

Monitoring apparatus (4) for monitoring a user's heart rate and / or heart rate variation, the apparatus comprising: a capacitor (22) which is position able on or near a body part of a person, for example a person's limb, for example an arm (3), such that an electrical capacitance of the capacitor (22) is influenced by blood pressure pulses of blood running through the body part, wherein, the apparatus (4) further comprises a data processor (26) for determining the heart rate and / or heart rate variation from changes in the capacitance of the capacitor (22).

Description

technical field [0001] The present invention relates to a monitoring device for monitoring a user's heart rate and / or heart rate variation. [0002] Devices for monitoring a user's heart rate and / or changes in heart rate typically have medical applications, for example to determine the occurrence and / or likelihood of heart failure. [0003] Such devices are also used by athletes, for example in training regimens. Background technique [0004] A monitoring device is known from US patent document US 3838684 . The monitoring device includes a pressure sensitive sensor that is applied to a portion of the skin surface during use for measuring heart rate. The pressure pulses picked up by the sensor are converted into electrical pulses. Additionally, a light source is provided that allows the user to count the pulses of light representing each heartbeat over a 15 second interval, thereby visually determining what their heart rate is at any given moment. The device is compact an...
