This paper presents an electroencephalogram (EEG) acquisition and biomarker-extraction system based on flexible, thin-film electronics. There exist commercial, single-use, flexible, pre-gelled electrode arrays; however, these are fully passive, requiring cabling to transfer sensitive, low-amplitude signals to external electronics for readout and processing. This work presents an active EEG acquisition...
This paper presents a flexible 40×40cm2 gesture-sensing sheet for large-area interactive-spaces. The system achieves out-of-plane sensing to 16cm. Self-capacitance readout of individual electrode pixels in a 4×4 array enables multiple gestures to be sensed simultaneously without ghost effects. For high-sensitivity readout, pixel self capacitance is converted to frequency via high-Q LC oscillators...
