1. A capacitive imaging glove comprising:
a plurality of electrodes implemented throughout the capacitive imaging glove including a first electrode and a second electrode;
a plurality of drive-sense circuits (DSCs), wherein:
a first DSC of the plurality of DSCs, when enabled, configured to:
drive a first signal to the first electrode via a first single line and simultaneously to sense the first signal via the first single line; and
generate a first digital signal representative of first one or more electrical characteristics of the first electrode;
a second DSC of the plurality of DSCs, when enabled, configured to:
drive a second signal to the second electrode via a second single line and simultaneously to sense the second signal via the second single line; and
generate a second digital signal representative of second one or more electrical characteristics of the second electrode;
memory that stores operational instructions; and
one or more processing modules operably coupled to the plurality of DSCs and the memory, wherein, when enabled, the one or more processing modules configured to execute the operational instructions to:
process the first digital signal representative of the first one or more electrical characteristics of the first electrode to determine the first one or more electrical characteristics of the first electrode;
process the second digital signal representative of the second one or more electrical characteristics of the second electrode to determine the second one or more electrical characteristics of the second electrode; and
generate capacitive image data representative of a shape of the capacitive imaging glove based on the first one or more electrical characteristics of the first electrode and the second one or more electrical characteristics of the second electrode.
