In an astonishing announcement, Neuralink has demonstrated how one of its implants is being used to give a paralysed man the ability to use computers using only his thoughts. What challenges do medical implants present for engineers, what did Neuralink demonstrate, and how could it change the future of medical science and accessibility?
What challenges do medical implants present to engineers?
While it may be hard to believe, medical implants date back thousands of years, with some of the earliest implants consisting of coins bolted into the skull to cure ongoing headaches. These early devices would have been more likely to cause harm than good, and while modern technology has certainly improved significantly, engineers still face a wide range of challenges with implants.
One of the primary challenges engineers face when developing medical implants is ensuring the safety and efficacy of the device. Implants, especially those that interact directly with the brain or nervous system, must be designed with precision and accuracy to avoid causing harm to the patient. For example, electrodes inserted into the brain must ensure that they do not sever neuron links, nor must they accidentally induce voltages that may otherwise cause uncontrollable actions and/or permanent damage.
Secondly, engineers need to also consider the biocompatibility of the materials used in the implant. Most materials, when implanted in the body, will trigger a immune response which can lead to rejection or inflammation. If left untreated, this can result in serious complications, including sepsi. Therefore, selecting materials that are biocompatible and non-toxic is crucial in ensuring the long-term success of the device and patient.
Another significant challenge engineers face is ensuring the reliability and longevity of the implant. Medical implants are often intended to remain in the body for extended periods, and as such, they must be durable and resistant to wear and tear. Additionally, the implant must be able to function consistently over time, providing reliable data and performance without degradation.
Finally, the ethical considerations surrounding medical implants add another layer of complexity for engineers. Issues such as patient privacy, data security, and informed consent must be carefully addressed to ensure that the implant is used responsibly and ethically. Engineers developing medical implants must work closely with medical professionals, ethicists, and regulatory bodies to navigate these complex ethical considerations.
Neuralink’s Ground-breaking Demonstration – Implanted Device In Brain
In what can only be described as a shocking reveal, Neuralink recently showcased a remarkable demonstration of its implant technology by enabling a paralyzed individual to control a computer cursor using only his thoughts.
The recent Neuralink demonstration, where Noland Arbaugh, paralysed below the shoulders, managed to play chess online using a brain-chip implant, marks a significant milestone in neural engineering and medical science. This achievement not only showcases the potential for brain-computer interfaces (BCIs) to restore independence to individuals with severe mobility impairments but also highlights the advanced safety and precision engineering of Neuralink’s technology. Such developments are crucial in addressing the complex challenges of integrating technology with the human nervous system.
The implant, developed by Neuralink, is a tiny device that measures around 23mm in diameter and is inserted into the skull. It utilises microscopic wires inserted into brain matter that are capable of reading neuron activity and transmitting wireless signals to a receiving unit.
During a live stream on X, formerly Twitter, Noland Arbaugh, who was paralyzed below the shoulders due to a diving accident, used the cursor controlled by the implant to play chess online. Mr. Arbaugh also mentioned that he was able to play the video game Civilization VI for eight hours straight, thanks to the brain implant.
