Abstract
An impact detection device for detecting impacts to a body part of a user and various supporting systems are discussed. In an example, an impact detect device can include a circuit board, a component having a first section and a second section, a battery, and a molding for housing the circuit boat, the battery and the component. The circuit board can include impact detection circuitry including at least two sensors and a communication circuit. A zone of reduced rigidity can connect the first and second sections of the component, with the circuit board secured to the first section. The battery can be secured to the second section of the component allowing for flex relative to the circuit board. The molding can be shaped and dimensioned for mounting to a body part of the user.
