A real-time emotion detection system based on electroencephalogram (EEG) measurement has been realised by means of an emotion detection headband coupled with printed signal acquisition electrodes and open source signal processing software (OpenViBE). Positive and negative emotions are the states classified and the Theta, Alpha, Beta and Gamma frequency bands are selected for the signal processing...
This paper reports, for the first time, a dispenser printed proximity sensor on fabric for wearable creative applications. The entire proximity sensor is dispenser printed onto a woven polyester/cotton fabric which is the predominant fabric used for clothing. Dispenser printing of electronic functions on fabric allows for significantly greater design freedom compared to weaving or knitting. In addition,...
This paper reports a novel process for realising freestanding piezoelectric cantilevers printed on fabric for potential use as a wearable sensor. Piezoelectric cantilever structures were fabricated by screen printing a piezoelectric stack on top of a structural layer that is supported by a sacrificial material during printing. The sacrificial layer was subsequently removed in an oven at 160 °C for...
This paper reports, for the first time, capacitive freestanding cantilever beams fabricated by screen printing sacrificial and structural materials onto a fabric/textile. Unlike traditional weaving process, the device will be screen printed layer by layer with desired pattern onto the fabric substrate. Free standing structures will be fabricated directly onto fabrics rather than other methods such...
