Abstract

Emotion-sensing is an important part in human computer interaction. Electrodermal activity measurement has been employed for a while to sense emotion. In this paper, the authors combine EDA, mobile technology, and flexible PCB substrate to implement a low power, compact emotion sensor which can be displayed on a smartphone. The flexible PCB circuit and sensing electrodes can be conformably wrapped around the user’s fingers to form a compact integrated unit. The 1st generation sensor has overall size 60 × 60 mm and consumes 90 mW under regular Bluetooth recording. In the newer version, we house the unit in a silicone mold to form a robust package for versatile sensing environment. With the new package, we were able to record 8-h sleeping patterns.
