Printed Electrodes with Memory Labels Embracing Body Coupled Communication: An Alternate M2M Communication Paradigm for Internet of Things
2015 (English)Manuscript (preprint) (Other academic)
A cost-effective concept of silicon-printed hybrid memory label for capacitive body coupled communication (BCC) is discussed in this paperin the context of internet of things (IoT). The strength of a hybrid approach is deliberated after careful review of organic thin film transistors (OTFTs) performance in the existing printed technologies. Further, the performance of battery operated baseband and passband communication architectures have experimentally been demonstrated for an alternate, short range, wireless, machine-to-machine (M2M) communication paradigm for smart phones platform, the capacitive BCC channel. The operating frequency range is from 100 kHz to 10 MHz for different body positions and printed electrodes configuration/sizes in conjunction with different output drivers. The transmission/reception of signals to the smart phone has been carried out through an SPI and Bluetooth interface to ensure that isolated earth ground conditions were guaranteed for capacitive BCC channel. The BCC passband communication architecture achieves 1 kbps while the digital baseband architecture achieves 100 kbps data rate for 10−2 packet error rate (PER) in the given experimental setup.
