Abstract
This system is a network of sensor nodes with multiple sensors at each node. The nodes are used in combination with a wearable garment to enable multiple types of data to be combined together to produce a fuller picture of a body's physiological state; such as during physical therapy. In addition, the system utilizes acoustic imaging to measure muscle activation. The system transmit this data to a host computer to visualize various data comparisons.
Claims11
A method comprising:
- forming a secure wireless network between a plurality of sensor nodes comprising an electrocardiogram, an electromyogram, and acoustic sensors;
- measuring muscle activation acoustically at each sensor node;
- transmitting muscle activation data from each of the plurality of sensor nodes to a master node;
- compiling the muscle activation data received from each of the plurality of sensor nodes;
- and
- creating a visual display comparing data from the plurality of sensor nodes captured during a selected span of time,
- wherein the sensor nodes are attached to a wearable garment of clothing at predetermined locations on the garment, and
- wherein the sensor nodes and master node are collectively configured to perform multilateration to locate an external acoustic source.
5 more elements
A wearable biofeedback system comprising:
- an article of clothing to which a plurality of sensor nodes are attached;
- a master node comprising a processor and a wireless antenna, whereby the master node is configured to receive and process data transmitted from all of the sensor nodes;
- the sensor nodes each comprising a plurality of sensors and a wireless antenna;
- the sensors at each sensor node comprising:
- a plurality of microphones, and
- one or more of a gyroscope and an accelerometer,
- wherein one of the plurality of microphones is positioned to face the user's body, and wherein another of the plurality of microphones is positioned to face away from the user's body;
- wherein the wireless antennas are configured to facilitate communication between the master and sensor node(s);
- and
- wherein the sensor nodes are attached to the article of clothing at predetermined locations on the article of clothing, and
- wherein the sensor nodes, each using its microphone that is positioned to face away from the user's body, are collectively configured to perform multilateration to locate an external acoustic source.
