This paper reports the demonstration of human integrated electronic devices, such as oscillators and RC filters, by utilizing flexible capacitor fabricated using few layer MoS2 grown on Al foil via hydrothermal method as electrodes and cellulose paper as a dielectric material. There are no reports of MoS2 on flexible substrate being utilized as capacitor electrode and further applied human interactive devices. Advantage of using MoS2 on Al foil is the enhanced capacitance upon strain due to the piezoelectric property of few layered MoS2 over monolayer MoS2. As the applied strain increases, increase in the capacitance was observed, which is systematically explained by piezoelectric property of MoS2, change in physical dimensions, and air gap between MoS2-Al foil and cellulose paper. Upon application of external strain on capacitor, range of frequencies can be generated by oscillator circuit and the mathematical operations such as differentiation and integration are observed for different input signal using RC filter circuits. Further, the fabricated flexible MoS2 capacitor was integrated to human hand and the corresponding frequency modulation with hand movement was recorded. Such a simple technique for fabrication of flexible variable capacitor is a major step ahead in wearable electronics having applications in digital electronics and sensors. © 2002-2012 IEEE.
