Bioelectromagnetic Simulation: Bridging Medical Imaging, Safety, and Wireless Device Performance
Bioelectromagnetic refers to the study of interactions between electromagnetic fields and the human body. This field is significant in various domains, including medical applications, safety considerations, and the performance of wireless communication devices. Simulation plays an important role in bioelectromagnetic studies due to the limitations of conducting measurements within the human body.
In medical applications, bioelectromagnetic simulation plays a crucial role in both imaging, as seen in techniques like MRI (Magnetic Resonance Imaging), and therapeutic treatments. When safety is involved, bioelectromagnetic simulation evaluates the potential risks of electromagnetic radiation from sources like cell phones or electric vehicles when in contact with the human body.
Additionally, bioelectromagnetic simulation is also relevant for understanding the wireless communication performance of devices such as smartwatches or wireless headphones, as the presence of the human body will affect the antenna’s performance.

Antenna Radiation Patterns in Wearable Devices: Impacts and Considerations
The antenna radiation pattern is a crucial factor in antenna design. Typically, we simulate these patterns in open, unobstructed spaces. Nevertheless, the surrounding environment can significantly influence the antenna pattern. Therefore, when creating a wearable device, it’s essential to ensure reliable communication performance not only when worn but also when the device is stationary on the surface or being charged.
In the following instance, we observe a Bluetooth patch antenna positioned near the human body. The below image depicts the simulated antenna radiation pattern and its efficiency concerning the distance between the antenna and the body.
