Abstract:
The natural interface for communicating with ambient intelligence is human touch. Nevertheless, because they rely only on physical contact, existing solutions that combine wireless transmission with touch sensing are limited in terms of selectivity and security. Information leakage is creatively reduced by Electro-Quasistatic Human Field Communication (EQ-HFC) technology, which establishes a conductive transmission link between touch sites and receivers. This method operates at low frequencies to allow EQ-HFC to function well by minimizing physical channel loss through the use of advanced design principles such as capacitive coupling and voltage reference operation. In order to improve the effectiveness and security of Person-to-Merchant (P2M) transfers, researchers are looking into the possibility of Person-to-Person (P2P) technologies, which include systems like payment gateways and healthcare data transmission via human touch. This study assesses several data transmission techniques in relation to a number of variables, including data size, transmission speed, and transmission medium. We investigate both capacitive and galvanic coupling in terms of several parameters. Galvanic coupling is a promising alternative for secure data transfer because it has been proved to be safe for human tissue and to not cause any negative consequences. Additionally, EQ-HFC technology integration might greatly improve security and user experience in common applications. In the healthcare industry, for instance, it may guarantee that private patient information is transferred safely and only when required, lowering the possibility of data breaches. Comparably, employing human touch for verification in place of more conventional techniques may provide a higher degree of security in financial transactions. By improving these technologies and making them more resilient and flexible for a variety of uses, continued research and development in this area hopes to close the gap between sophisticated data transmission techniques and human interaction.
