1. A dynamically formable electrodermal activity (EDA) sensor, comprising:
a dynamically formable base comprising a soft robotics material, wherein the dynamically formable base comprises a formable surface configured to be dynamically formed in response to input signals;
an EDA sensing layer affixed to the formable surface of the dynamically formable base, the EDA sensing layer comprising a plurality of sensors connected to a power supply, each sensor of the plurality of sensors comprising a pair of electrodes arranged on a common surface of a flexible substrate affixed to the formable surface of the dynamically formable base;
an actuation layer comprising a plurality of touch-sensitive actuation points, the actuation layer disposed between the EDA sensing layer and the formable surface, and
a processor configured to determine an EDA of a user based on EDA measurements from the EDA sensing layer, wherein the input signals are based on the determined EDA of the user,
wherein, in response to the input signals, the formable surface of the dynamically formable base and the EDA sensing layer affixed thereto are reformed into a desired contour.
