1. A multimodal measurement system comprising:
a wearable assembly configured to be worn by a user; and
a module configured to be removably inserted into the wearable assembly and comprising:
a housing,
a printed circuit board (PCB) housed within the housing, and
a light guide assembly configured to emit light directed at a target within the user, the light guide assembly comprising:
a lower light guide portion housed within the housing and having a proximal end attached to the PCB,
a conductive spring member housed within the housing and comprising a coil positioned around an external surface of the lower light guide portion, and
a conductive upper light guide portion connected to the lower light guide portion and configured to protrude from an upper surface of the housing and be in contact with a surface of a body of the user, the conductive upper light guide portion conductively coupled to circuitry on the PCB by way of the conductive spring member and configured to function as an electrode that detects electrical activity of the target.
