Abstract
A wearable sensor device includes a liquid metal wire that includes an elongated tube with an internal cavity having a uniform cross-sectional geometry, the internal cavity is at least partially filled with liquid metal. The wearable sensor device further includes detection circuitry to detect a change in an electrical attribute of the liquid metal wire based on a temporary change in the cross-sectional geometry, and generate sensor data to identify an event associated with a wearer of the wearable device based on the temporary change in the cross-sectional geometry.
Claims20
An apparatus comprising:
- a wearable device comprising:
- a liquid metal wire comprising an elongated elastomeric tube with a tubular external surface and an internal cavity with a uniform cross-sectional geometry, wherein the internal cavity is at least partially filled with liquid metal;
- and
- detection logic comprising hardware circuitry to:
- detect a change in an electrical attribute of the liquid metal wire based on a temporary change in the cross-sectional geometry;
- and
- generate sensor data to identify an event associated with a wearer of the wearable device based on the temporary change in the cross-sectional geometry.
A garment comprising:
- a liquid metal wire fixedly attached to the garment, wherein the liquid metal wire comprises an elongated elastomeric tube with an internal cavity forming an internal volume, and at least a portion of the internal volume of the elastomeric tube is partially filled with liquid metal;
- and
- a connector fixedly attached to the garment, wherein the connector comprises:
- a liquid metal wire interface comprising:
- a solid conductive element;
- a reservoir with an internal volume, wherein at least a portion of the solid conductive element is positioned within the internal volume, an end of the liquid metal wire is connected to an opening of the reservoir to form a contiguous volume comprising the internal volume of the internal cavity and the internal volume of the reservoir, wherein the liquid metal is to contact the portion of the solid conductive element;
- and
- a receptacle fixedly attached to the garment to couple to the liquid metal wire interface, wherein the receptacle is to removably connect to a sensor device, and an electrical connection is established between the sensor device and the liquid metal wire when the sensor device is connected to the receptacle.
A system comprising:
- a wearable sensor device comprising:
- a liquid metal wire comprising an elongated elastomeric tube with a tubular external surface and an internal cavity with a uniform cross-sectional geometry, wherein the internal cavity is at least partially filled with liquid metal;
- and
- sensor circuitry to:
- detect a change in an electrical attribute of the liquid metal wire based on a temporary change in the cross-sectional geometry;
- and
- generate sensor data to identify the change in the electrical attribute;
- and
- a data processing device comprising:
- a processor;
- and
- biometric detector executable by the data processor to:
- receive the sensor data;
- and
- determine from the sensor data that the change in the electrical attribute corresponds to a biometric of a wearer of the wearable sensor device.
