Abstract: Electric fields that can cause corrosion of contacts can be compensated for by embodiments of the present invention. For example, voltage waveforms at the contacts can be made to have a zero volt average, and therefore have a zero net electric field. Galvanic voltages generated by dissimilar metals used by a contact and a housing can generate an electric field, and currents motivated by the galvanic electric field can be blocked by capacitively coupling the contacts to their corresponding circuits.

Abstract: Bands for wearable devices include multiple band retainers used to maintain engagement between an assembly (e.g., a pair) of bands. Some band retainers may be permanently affixed with the band at a certain location of the band, while other band retainers can be removable. The removable band retainers can be moved to different locations of the band, thus allowing the band retainer to retain another band at different locations. As a result, the assembly of bands can be used with different users, and in particular, users with different wrist sizes. Moreover, using multiple band retainers can provide an engagement force between the bands to withstand higher-impact events, such as swimming and diving. Additionally, bands and band retainers may include one or more liquid-resistant and corrosion-resistant materials.
