What is Human Intranet?

The world around us is getting a lot smarter quickly: virtually every single component of our daily living environment is being equipped with sensors, actuators, processing, and connection into a network that will soon count billions of nodes and trillions of sensors. These devices only interact with the human through the traditional input and output channels. Hence, they only indirectly communicate with our brain—through our five sense modalities—forming two separate computing systems: biological versus physical. It could be made a lot more effective if a direct high bandwidth link existed between the two systems, allowing them to truly collaborate with each other and to offer opportunities for enhanced functionality that would otherwise be hard to accomplish. The emergence of miniaturized sense, compute and actuate devices as well as interfaces that are form-fitted to the human body opens the door for a symbiotic convergence between biological function and physical computing.

Human Intranet is an open, scalable platform that seamlessly integrates an ever-increasing number of sensor, actuation, computation, storage, communication and energy nodes located on, in, or around the human body acting in symbiosis with the functions provided by the body itself. Human Intranet presents a system vision in which, for example, disease would be treated by chronically measuring biosignals deep in the body, or by providing targeted, therapeutic interventions that respond on demand and in situ. To gain a holistic view of a person’s health, these sensors and actuators must communicate and collaborate with each other. Most of such systems prototyped or envisioned today serve to address deficiencies in the human sensory or motor control systems due to birth defects, illnesses, or accidents (e.g., invasive brain-machine interfaces, cochlear implants, artificial retinas, etc.). While all these systems target defects, one can easily imagine that this could lead to many types of enhancement and/or enable direct interaction with the environment: to make us humans smarter!

Here, in our projects, we mainly focus on sensor, computation, communication, and emerging storage aspects to develop very efficient closed-loop sense-interpret-actuate systems, enabling distributed autonomous behavior.

Brain-Machine Interfaces and wearables

In ear EEG.jpg


Short Description

Noninvasive brain–machine interfaces (BMIs) and neuroprostheses aim to provide a communication and control channel based on the recognition of the subject’s intentions from spatiotemporal neural activity typically recorded by EEG electrodes. BMIs are a special kind of HMI, focused on the brain. What makes BMIs particularly challenging is their susceptibility to errors over time in the recognition of human intentions.

In these projects, our goal is to develop efficient and fast learning algorithms that replace traditional signal processing and classification methods by directly operating with raw data from electrodes. Furthermore, we aim to efficiently deploy those algorithms on tightly resource-limited devices (e.g., Microcontroller units) for near sensor classification using artificial intelligence.

Epilepsy Seizure Detection Device

Non-EEG Seizure.jpg NeuroPace.jpg

Short Description

Epilepsy is a brain disease that affects more than 50 million people worldwide. Conventional treatments are primarily pharmacological, but they can require surgery or invasive neurostimulation in the case of drug-resistant subjects. In these cases, personalized patient treatments are necessary and can be achieved with the help of long-term recording of brain activity. In this context, seizure detection systems hold promise for improving the quality of life for patients with epilepsy, providing non-stigmatizing and reliable continuous monitoring during real-life conditions. In this project, our goal is to develop efficient techniques for EEG as well as non-EEG signals to detect an upcoming seizure in an ultra-low-power device. In this project, our goal is to develop efficient techniques for EEG as well as non-EEG signals to detect an upcoming seizure in an ultra-low-power device. This covers a wide range of analog and digital techniques.

Foundation models and LLMs for Health

Short Description

Incorporating Foundation Models and Large Language Models (LLMs) within artificial intelligence is gaining significant traction, particularly due to their potential applications in the health sector. This project is dedicated to developing sophisticated methodologies for utilizing foundation models and LLMs in health-related applications, specifically analyzing electroencephalogram (EEG) brain signals.

In healthcare and biomedical research, implementing advanced computational models, notably Foundation Models and Large Language Models (LLMs), revolutionizes the understanding and interpretation of intricate biosignals. We stand at the vanguard of this revolutionary change, delving into the capabilities of these models for the analysis and interpretation of critical biosignals, including electroencephalograms (EEG) and electrocardiograms (ECG).

Foundation Models, encompassing a spectrum of robust, pre-trained models, are transforming our ability to process and interpret large datasets. Initially trained on extensive and diverse datasets, these models are adaptable for specific tasks, offering remarkable accuracy and efficiency. This adaptability renders them particularly beneficial for biosignal analysis, where the intricacies of EEG and ECG data demand both precision and contextual understanding.

As a subset of Foundation Models, LLMs have demonstrated efficacy in processing and generating human language. At IIS, we are pioneering the application of LLMs in the domain of biosignal interpretation, extending beyond textual data. This entails training the models to interpret the 'language' of biosignals, translating complex patterns into actionable insights.

Our emphasis on EEG and ECG signals is motivated by these biosignals' profound insights into human health. EEGs, capturing brain activity, and ECGs, monitoring heart rhythms, are instrumental in diagnosing and managing various health conditions. By leveraging Foundation Models and LLMs, our objective is to refine diagnostic accuracy, predict health outcomes, and customize patient care.

IIS invites Master's students to immerse themselves in this pioneering area. Our projects offer avenues to engage with state-of-the-art technologies, apply them to real-world health challenges, and contribute to shaping a future where healthcare is more predictive, preventive, and personalized. We encourage your participation in this exhilarating endeavor to redefine the confluence of healthcare and technology.
