Due to increased demand for wearable technology along with further technological development of the sensors, the application areas of wearable sensors are anticipated to grow further.
  • a major challenge with such wearable technologies is to combine wear comfort with high quality measurement signals.
  • Many known systems for measuring physiological parameters may be perceived as uncomfortable by some users and/or they may lack signal quality.
  • a stable, but comfortable arrange- ment of the measurement electrodes remains a challenge.
  • systems for measuring the heart rate are known that may require a separate chest belt to be worn.
  • 2012/0238910A1 provide garments with holes for placing measurement electrodes through the holes on the user's skin.

  • the compression belt is integrated into the main body and comprises a second material, the second material being an elastic material.
  • the second elastic material has a second Young's modulus.
  • the second Young's modulus is preferably greater than the first Young's modulus. Accordingly, the second elastic material provides a higher elastic tensile force than the first material.
  • the compression belt comprises a plurality of portions, in particular a lower chest portion extending in a horizontal direction below a chest area of the wearer, a central chest portion extending vertically from a central area of the lower chest portion towards the neck of the wearer, a neck portion extending around the neck of the wearer and a back portion arranged in a back area of the wearer and extending from the neck portion to the horizontal portion.
  • the compression belt is configured to press the first electrode and the second electrode on the body of the wearer.
  • the combination of an integrated compression belt and the main body ensures an accurate, reliable and stable position of the first and the second electrode. Furthermore, forming the garment by a plurality of garments parts facilitates ease of fabrication. This allows e.g. to prefabricate the sensory part, the elastic main body and the parts of the compression belt separately.
  • the garment according to embodiments of the invention uses a smart combination of a main body, in particular an elastic main body, and an inte- grated compression belt to provide on the one hand a stable position of the first and the second electrode with sufficient contact pressure and to facilitate on the other hand this stable position during movements of the user.
  • the compression belt establishes a kind of rack or skeleton of fixed/stable anchor points/anchor areas around the chest of the user and in particular around the sensory part to ensure a stable position of the sensory part.
  • the compression belt may according to embodiments also denoted as chest belt.
  • the main body acts as intermediate between these anchor points/anchor areas and facilitate a movement of the body of the user while the compression belt and the sensory part may remain in a substantially stable position with respect to the body of the wearer.

  • Such design of the material properties by means of the Young's modulus provides a particularly advantageous interaction of the compression belt and the main body that facilitates a stable position of the first electrode and the second electrode with sufficient contact pressure despite movements of the wearer.
  • the Young's modulus is a property of elastic materials indicating a ratio of change in stress to change in strain within the elastic limits of the respective elastic material.
  • the ratio may be derived from the stress expressed in force unit cross-sectional area and the strain expressed as a fraction of original length.

  • the compression belt is applied to the outer face of the main body.
  • the complete main body can be prefabricated in one piece and then the compression belt can be attached to/fixed to the outer face of the main body.
  • This provides the further advantage that there are no seams on the inner face which provides ease of wear.
  • it facilitates the attachment of the sensory part on the inner face, opposite to the horizontal portion of the compression belt. In other words, on one side of the main body below the chest of the wearer there is the horizontal portion of the compression belt and on the other oppo- site side there is the sensory part.
  • the compression belt is applied to the main body by gluing. This facilitates an efficient and reliable fabrication.
  • the sensory part is applied to the main elastic body by gluing.
  • the compression belt comprises a plu- rality of compression parts.

  • At least some of the plurality of com- pression parts are spaced apart from each other such that elastic areas of the main body are formed between the respective compression parts.
  • Such an embodiment allows to tune the elastic properties of the compression belt by combing the Youngs" s moduli of the main body (in the intermediate areas between the spaced apart compression parts) and of the compression parts.
  • the sensory part comprises a base layer and a conductive layer arranged on the base layer, the conductive layer comprising the first electrode, the second electrode, the first electrode lead and the second electrode lead.
  • the conductive layer is glued on the base layer.
  • the conductive layer comprises a conductive fabric or a conductive material for either wet or dry sensor measurements.
  • the garment is configured to provide at least a predetermined minimum body pressure of 10 mmHG, in particular of more than 20 mmHG, on the body of the user.
  • minimum body pressure facilitates that the garment provides fixed/stable anchor points/anchor areas around the sensory part. Thereby stable electrode position and hence a reliable measurement is facilitated.
  • the garment is configured such to provide at least a pre- determined minimum contact pressure of 10 mmHG and even more preferably of more than 20 mmHG, on the electrodes.
  • Such contact pressure facilitates a stable electrode position and hence a reliable measurement.
  • the contact pressure of the first electrode and the second electrode and the body pressure respectively depends on the Young's modulus, the elongation and the relaxation time of the fabrics used for the various parts of the garment. Generally, the higher the Young's modulus, the higher the body pressure.
  • the body pressure may also be referred to as clothing pressure.
