Near-field radio sensors can be implemented both as wearables for continuous monitoring and as furnishing attachments for covert operation, without requiring skin touch, enabling convenient deployment and high user comfort. The sensor can output cardiac and respiratory waveforms, systemic pulses, muscle contraction, eye movement, and tissue vibration for various biomedical, biological, and cyberphysical applications. The radio signal can go through layers of fabrics or animal surface coverings with little loss or dispersion to couple directly inside the living body. We will illustrate the theory, design variations, and verified results, and discuss present limitations and outlooks for technology adoption in practical scenarios.
