TI  - A Wearable Hydration Sensor with Conformal Nanowire Electrodes.
LID - 10.1002/adhm.201601159 [doi]
AB  - A wearable skin hydration sensor in the form of a capacitor is demonstrated based 
      on skin impedance measurement. The capacitor consists of two interdigitated or 
      parallel electrodes that are made of silver nanowires (AgNWs) in a 
      polydimethylsiloxane (PDMS) matrix. The flexible and stretchable nature of the 
      AgNW/PDMS electrode allows conformal contact to the skin. The hydration sensor is 
      insensitive to the external humidity change and is calibrated against a 
      commercial skin hydration system on an artificial skin over a wide hydration 
      range. The hydration sensor is packaged into a flexible wristband, together with 
      a network analyzer chip, a button cell battery, and an ultralow power 
      microprocessor with Bluetooth. In addition, a chest patch consisting of a strain 
      sensor, three electrocardiography electrodes, and a skin hydration sensor is 
      developed for multimodal sensing. The wearable wristband and chest patch may be 
      used for low-cost, wireless, and continuous monitoring of skin hydration and 
      other health parameters.
