A wearable heart activity sensor device includes a substrate of optically transparent material arranged to face a skin of a user when the sensor device is worn by the user, at least one light emitting diode, LED, arranged on the substrate and arranged to emit light through the substrate, at least one photo sensor arranged on the substrate as spatially separated from the at least one LED and arranged to absorb light through the substrate, wherein the at least one LED and the at least one photo sensor are included in a photoplethysmogram sensor of the heart activity sensor device, and an overmold of thermoplastic material covering the at least one light emitting diode, the at least one photo sensor and a space between the at least one light emitting diode and the at least one photo sensor.

A watch strap includes a substantially inflexible main portion, a flexible auxiliary portion coupled to the substantially inflexible main portion, and a tightener coupled to the flexible auxiliary portion. When in use, the tightener is configured to maintain a selected tightness, and the flexible auxiliary portion is configured to be elastic.

Watch strap

An electrode belt includes at least one electrode to measure biometric signals related to heart activity of a user, a non-conductive strip having at least one opening, and a flexible strip to enable placement of the electrode belt against the skin of the user. The non-conductive strip is coupled with the flexible strip such that, when in use, the at least one electrode is in physical contact with the skin of the user.

Enhancing physical activity measurement

The invention relates to a case structure for a sensor structure attachable to and detachable from a shoe, the case structure comprising a case and an attachment arrangement for attaching the case to the shoe, the attachment arrangement comprising an attachment projection structure intended to attach the case to the shoe such that shoelaces remain between a bottom comprised by the case and the attachment projection structure below the bottom. The essential feature in the invention is that the attachment projection structure is a branched projection structure comprising a first projection branch and a second projection branch, and, between the projection branches, an intermediate area intended to enable the placing of the case structure in position even if the shoelaces were arranged to support a tongue of the shoe.
