What is provided is a wearable, hands-free emergency alert device that responds automatically to a measurable physical effect of a fall event by the wearer to send an alert signal to a remote responder. The wearable device may be a bracelet with a flex circuit including an accelerometer; a manual alert to signal non-fall emergencies; a microphone and/or audio chip for voice communications between the user of the wearable device and a remote responder; one or more charging contacts so as to allow for induction and/or wireless charging of the device; and a wireless transmitter capable of sending a wireless alert signal in response to a sensed fall and capable of generating a response signal in response to receipt of a ping signal which may be used to determine the device's location. |
