(A) Schematic illustration of the fabrication processes of the multifunctional wearable electronics. (B) Motion tracking performance with the multifunctional device worn on the wrist. (C) Indoor and outdoor body temperatures acquired using the wearable electronics mounted on the forehead (top) and comparison of measured indoor body temperatures when the wearable electronics is mounted at different locations (bottom). (D) Acoustic data acquired using the wearable electronics mounted on the neck. (E) ECG data acquired using the wearable electronics when the participant is at rest (top), and after exercising for 13 s (middle) and 34 s (bottom).

(A) Step-by-step process of each layer of the device to allow multiple functionalities and wearability. (B) Amplitude vs. Time graph of sensor worn on the wrist to measure motion when walking, running, jumping. (C) Thermal sensor can read forehead, abdomen, and hand temperature on skin when indoor and outdoor over time. (D) The acoustic sensor is placed on the neck to measure the amplitude (vibration) characteristics of the vocal chords to serve as a human-machine interface. (E) The electrocardiogram sensor measures heart activity while resting, after exercising for 13 seconds and then after 34 seconds. The heart rate resulted in 72, 96, and 114 per minute, respectively.
