Development of a low-power input stage for Body-Coupled Communication

Introduction

Traditional Intra-Body Communication approaches mostly rely on either cable joints embedded in clothing, or on wireless radio transmission that tends to reach beyond the body. Situated between these two approaches is Body-Coupled Communication, a promising technique that transmits information across the user's skin. The use of the human body as a bounded medium minimizes security concerns, significantly reduces the energy consumption of data transmission, and enables several new applications which have not been possible before.

Description

During your thesis, you are part of a team of motivated, young, and internationally oriented researchers. You are exploring the principle of Body-Coupled Communication and designing an analog circuit for the input stage of a receiver device. The implementation includes the use of operational amplifiers and filters to capture the signal and, eventually, to apply signal preconditioning and preprocessing. The circuit is developed with a focus on energy efficiency and reliability which finally is evaluated.

Tasks and Requirements

• Hardware design and implementation
• Analog input stage of a receiver device
• Signal capturing, preconditioning, and preprocessing
• Operational amplifiers and filters
• Evaluation of reliability and energy efficiency
• Body-Coupled Communication
• Sustainable development and documentation
• Motivated and independent working
