The development of modern implantable electronic devices has been stagnant due to signal transmission problems compared to the recent development of wearable devices and artificial intelligence.

The development of modern implantable electronic devices has been stagnant due to signal transmission problems compared to the recent development of wearable devices and artificial intelligence. Most implanted electronic devices used in medical applications transmit data slowly over radio frequencies below 50 kbs per second. At this rate, it takes a long time for doctors to transmit data and update devices.
Andrew Singer, an electrical engineer from the University of Illinois at Urbana-Champaign, is determined to find a more efficient way of communicating than radio waves. His research team found that ultrasound signals can transmit signals through muscles at 30 mbps per second. This is the highest speed known to transmit signals through biological tissue. Comparing the transfer rate of 25 mbps per second required to view ultra clear video on Netflix, 30 mbps per second provides a lot of room for imaging applications.
From a physical point of view, radio waves are electromagnetic waves of a specific frequency band and are generated by electromagnetic induction. Ultrasound is a sound wave that exceeds the upper limit of the human ear and is generated by mechanical vibration.
Currently, most implantable electronic devices transmit data over radio frequencies, with the highest frequency band not exceeding 300 kHz. The essence of radio waves is electromagnetic waves with a wavelength below 300 kHz. Electromagnetic waves above this frequency band become microwaves. Microwaves not only interfere with nearby electronic devices, but are also absorbed by the body during passage through the body of the implanted person. Not only will the signal be weakened, but more dangerously, the body will heat up after absorbing microwaves, just like the heating principle of a microwave oven.
Singer designed a series of experiments using pig's loin and bovine lungs to simulate the transmission of muscles, fats, and internal organs during signal transmission. It is hoped that ultrasound can be used to transmit data to implanted electronic devices, both to ensure transmission speed and not to be hindered.
Singer said that he is very satisfied with the results of the experiment. In the process of passing animal muscles, fat and internal organs, the ultrasonic signal not only spreads fast, but also achieves the goal of basic losslessness.
For Singer's experiments, radiologist Jeremy Dahl, who specializes in ultrasound instruments, raised some objections. In the experiment, the distance between the transmitter and the receiver was only 5.86 cm. Therefore, the experiment cannot prove that the ultrasonic wave can be successfully completed in the electronic device with a deep implantation position or the receiving device far from the implanter.
In addition, because they did not test the ultrasound-passing effect of the bone-containing part, the passage of ultrasound to bones and cartilage was temporarily unclear.
Another potential problem is that, unlike divergently transmitted radios, the transmission of ultrasound is in a single direction, so the doctor must know the specific location of the patient's implant to receive the signal. This can cause some inconvenience in using the actual application scenario.
Singer will continue to experiment with animals to complete. He believes that in the near future, through ultrasound signal transmission, doctors can let the patient swallow the camera and see the micro camera immediately through the digestive tract HD. While electronic devices have been implanted, it is expected that the update function can be upgraded by ultrasonic signals in the future.
