Abstract
An apparatus includes a plurality of substrates, configured to adhere to a body of a subject via respective pieces of adhesive material, and multiple coils coupled to the substrates, respectively. Other embodiments are also described.
Claims17
An apparatus, comprising:
- (a) a substrate, comprising:
- (i) a plurality of wide portions, configured to adhere to a body of a subject via respective pieces of adhesive material, and
- (ii) one or more flexible narrow portions, each flexible connector having a U-shape profile formed from a first linear section, a second linear section, and a connecting section coupling the first and second linear sections, each of which:
- is narrower than and connects a respective pair of successive ones of the wide portions to one another, and
- is configured to flex in response to movement of any one of the pair;
- (b) a plurality of coils, each coil of the plurality of coils being coupled to a respective wide portion of the plurality of wide portions;
- (c) a plurality of terminals, each terminal of the plurality of terminals extending from a respective coil of the plurality of coils, each terminal extending from a respective coil and into a common wide portion of the plurality of wide portions, at least one terminal of the plurality of terminal extending though a respective flexible narrow portion of the one or more flexible narrow portions;
- and
- (d) a processor configured to:
- (i) calculate an initial relative pose of the plurality of coils,
- (ii) calculate a subsequent relative pose of the plurality of coils, and
- (iii) generate an alert if the subsequent relative pose of the plurality of coils deviates from the initial relative pose of the plurality of coils.

Apparatus, comprising:
- (a) a plurality of substrates, configured to adhere to a body of a subject via respective pieces of adhesive material;
- (b) one or more flexible connectors coupled to and extending between adjacent substrates of the plurality of substrates, each flexible connector of the one or more flexible connectors being configured to flex in response to movement of the plurality of substrates relative to each other, each flexible connector having a U-shape profile formed from a first linear section, a second linear section, and a connecting section coupling the first and second linear sections;
- (c) a plurality of coils, each coil of the plurality of coils being coupled to a respective substrate of the plurality of substrates;
- and
- (d) a plurality of terminals, each terminal of the plurality of terminals extending from a respective coil into a common substrate of the plurality of substrates, at least one terminal of the plurality of terminals extends through a flexible connector of the one or more flexible connectors to extend into the common substrate of the plurality of substrates.
