1. A device comprising:
- one or more sensors configured to generate sensor data;
a controller configured to process the sensor data and generate processed sensor data;
an antenna configured to wirelessly transmit to an electronic device at least one of the sensor data or the processed sensor data; and
a body sized and shaped to wrap around a body part of an individual such that the device is wearable by the individual, wherein the body comprises an outer over-mold member, an inner over-mold member, a plurality of flex areas, an internal spine member extending through the body, and a flexible circuit member wrapped around and connected to the spine member;
wherein the internal spine member and the flexible circuit member are located between the outer over-mold member and the inner over-mold member such that the outer over-mold member and the inner over-mold member enclose the internal spine member and the flexible circuit member;
wherein the circuit member connects the one or more sensors to the controller and connects the controller to the antenna; and
wherein at least a portion of the antenna is located in one of the flex areas and the antenna is tuned such that the antenna operates at a peak resonant frequency when the body part is received by the device, the antenna operates at an off-peak resonant frequency relative to the peak resonant frequency when the body part is not received by the device, and the antenna produces a radiation pattern having relatively high gain areas that are directed away from the individual when wirelessly transmitting the processed sensor data, wherein the antenna is in resonance both when the body part is received by the device and when the body part is not received by the device.

Abstract
A wrist-worn device monitors movements of a user. A sensor assembly of the wrist-worn device is configured to detect movement of the user and generate sensor data based on the movement detected. A controller connected to the sensor assembly obtains movement data based on the sensor data. An antenna connected to the controller is configured to operate at a desired frequency when a wrist of the user is received by the device such that the movement data is wirelessly transmittable from the wrist-worn device to an electronic device. The antenna may exhibit a different design and configuration depending on the size of the wrist-worn device.
