The Takeaway

Researchers have demonstrated that microbubbles, often used in medical imaging, can act as physical information carriers to send signals through biological tissue. This 'bubble-based internet' could allow medical implants to communicate from deep within the body without the need for invasive wires or potentially harmful levels of radiation.

From the abstract

In-body communication is an upcoming field with significant implications for medical diagnostics and therapeutic interventions. Microbubbles have gained attention due to their distinct physical properties, making them promising candidates to facilitate communication within the human body. This work explores the use of microbubbles as communication carriers, with a particular focus on their detection and the application of a modulation scheme. Through experimental analysis the feasibility and eff
