1. A biometric measuring device for obtaining biometric measurements on a limb or digit of a subject, comprising:
- a rollable sleeve, wherein the rollable sleeve is rollable along a longitudinal axis of the limb or digit; and
a plurality of biometric sensors attached to the rollable sleeve, wherein;
one or more of the plurality of biometric sensors are positioned on the rollable sleeve within a rollable portion of the rollable sleeve,the one or more of the plurality of biometric sensors;
are positioned on an interior surface of the rollable sleeve, andcomprise an ultrasonic sensor, the ultrasonic sensor having a surface on which an acoustic matching layer is disposed; and
the rollable sleeve is configured to roll out over the limb or digit starting from an at least partially rolled up state in which at least a portion of the rollable sleeve containing the plurality of biometric sensors is at least partially rolled up defining an annular opening.

18. A method of measuring a biometric property of a subject using a biometric measuring device comprising a rollable sleeve and a plurality of biometric sensors attached to the rollable sleeve, wherein one or more of the plurality of biometric sensors are positioned on the rollable sleeve within a rollable portion of the rollable sleeve, and the one or more of the plurality of biometric sensors are positioned on an interior surface of the rollable sleeve, and comprise an ultrasonic sensor, the ultrasonic sensor having a surface on which an acoustic matching layer is disposed, and wherein the rollable sleeve is rolled out over the limb or digit starting from an at least partially rolled up state in which at least a portion of the rollable sleeve containing the plurality of biometric sensors is at least partially rolled up defining an annular opening, the method comprising:
-
receiving output signals from the plurality of biometric sensors attached to the rollable sleeve when the rollable sleeve is deployed on a limb or digit of the subject the output signals including output signals from the ultrasonic sensor; and processing the output signals to obtain one or more biometric measurements. - View Dependent Claims (19, 20, 21, 22)
