1. A wearable system, comprising:
a 3D-printed epidermal wearable microfluidic electronic skin configured to adhere to and conform with the contours of human skin;
an array of 3D-printed sensors integrated within the 3D-printed epidermal wearable microfluidic electronic skin;
at least two 3D-printed electrodes integrated within the 3D-printed epidermal wearable microfluidic electronic skin and configured to localized sweat induction;
a 3D-printed microfluidics component comprising multiple inlets configured to contact the human skin and collect a sweat sample from the human skin; and
a 3D-printed processor comprising non-transitory computer readable instructions to process data collected from the array of 3D-printed sensors.
