JOSEPH A. PARADISO

Alexander W. Dreyfoos Professor

Assoc. Academic Head, Program in Media Arts and Sciences

Massachusetts Institute of Technology

Joe Paradiso is the Alexander W. Dreyfoos (1954) Professor in Media Arts and Sciences at the MIT Media Lab, where he directs the Responsive Environments group and serves as the associate academic head.  He received his PhD in Physics from MIT in 1981 and a BSEE from Tufts University in 1977, and joined the Media Lab in 1994 after developing spacecraft control and diverse sensor systems at Draper Laboratory and high-energy physics detectors at ETH Zurich and CERN Geneva.  Much of his current research explores how sensor networks augment and mediate human experience, interaction and perception.  This encompasses wireless sensing systems, wearable and body sensor networks, energy harvesting and power management for embedded sensors, ubiquitous/pervasive computing and the Internet of Things, human-computer interfaces, space-based systems, and interactive music/media. He has written over 300 articles and papers in these areas.  In his spare time, he enjoys designing/building electronic music synthesizers, composing electronic soundscapes, and seeking out edgy and unusual music while traveling the world.

 

KEYNOTE: How We Will Connect To Our Networked Future in a Post-IoT World

​

We have already witnessed profound and often unanticipated developments as IoT is built out and the world is mediated via a mainly graphic wireless device held at arms length.  But what will happen once the world is precognitively interpreted by what we term ‘sensory prosthetics’ that change what and how humans physically perceive, a world where your own intelligence is split ever more seamlessly between your brain and the cloud?  Accordingly, this talk will overview the broad theme of interfacing humans to the ubiquitous electronic "nervous system" that sensor networks will soon extend across things, places, and people, going well beyond the ‘Internet of Things,’ challenging the notion of physical presence and the boundary of self.  I'll illustrate this through two avenues of research - one looking at a new kind of digital "omniscience" (e.g., different kinds of browsers for sensor network data & agile frameworks for sensor/data representation) and the other looking at buildings & tools as "prosthetic" extensions of humans (e.g., making HVAC and lighting systems an extension of your natural activity and sense of comfort, or smart tools as human-robot cooperation in the hand), drawing from many projects that are running in my group at the MIT Media Lab and touching on technical areas ranging from low-power wearable sensing/robotics to cognitive audio and distributed sensor networks.

Wearable Sweat Sensors for Personalized Health Monitoring

The rising research interest in personalized and precision medicine promises to revolutionize traditional medical practices. This presents a tremendous opportunity for developing wearable devices toward predictive analytics and treatment. In this talk, I will introduce fully-integrated flexible biosensors for multiplexed in-situ perspiration analysis, which can selectively and accurately measure a wide spectrum of sweat analytes (e.g., metabolites, electrolytes, heavy metals, drugs and other small molecules). This platform allows us to gain real-time insight into the sweat secretion and gland physiology. I will also demonstrate an integrated wearable sweat extraction and sensing system which can be programmed to induce sweat on demand with various secretion profiles. To demonstrate the clinical value of our wearable sweat sensing platform, human subject studies were performed toward fitness monitoring, physiological monitoring, cystic fibrosis diagnosis and drug monitoring. These wearable and flexible devices open the door to a wide range of personalized monitoring and diagnostic applications.

Redefining Noise: Finding Unintended Signals Everywhere

We are surrounded by noise everywhere. Sensing and signal processing is often focused on filtering out this noise in order to capture some signal of interest. In this talk, I will explore using signals that were traditionally considered noise and looking more deeply into these signals in order to utilize them for energy monitoring, activity recognition, and gesture recognition. The talk will focus on my past work looking at electrical noise, both conducted and radiated, but I will also generalize the approach of looking for signals within the noise, which can be applied to other signal types and application domains.

Wireless Electronic Tattoos for Personalized Mobile Sensing and Therapeutics

Merging the human body with electronics and machines can enable internet of health (IoH), human-machine interface (HMI), as well as augmented human capabilities. However, bio-tissues are soft, curvilinear, and dynamic whereas wafer-based electronics are hard, planar, and rigid. Over the past decade, stretchable high-performance inorganic electronics have emerged as a result of innovative structural designs and fabrication processes. In particular, epidermal electronics, a.k.a. electronic tattoos (e-tattoos) represent a class of noninvasive stretchable circuits, sensors, and stimulators that are ultrathin, ultrasoft and skin-conformable. Our group has invented a dry and freeform “cut-solder-paste” method for the rapid prototyping of wireless stretchable e-tattoos. The e-tattoos can be applied for electrophysiology (e.g. ECG, EEG, EMG, EOG, etc.), mechanophysiology (e.g. respiration, seismocardiogram, etc.), thermophysiology, photoplethysmography (PPG) etc.. The e-tattoos can also be used as personalized treatment and therapeutic device. For wireless operation, we leverage Bluetooth low energy (BLE) for wireless data transfer and near field communication (NFC) for wireless charging. A strategy to wirelessly charge e-tattoos on-the-go will also be introduced.

Brain-Machine Interfaces: Beyond the Clinical Realm

​

A brain-machine interface (BMI) is a system that enables users to interact with computers and robots through the voluntary modulation of their brain activity. Such a BMI is particularly relevant as an aid for patients with severe neuromuscular disabilities, although it also opens up new possibilities in human-machine interaction for able-bodied people. I will discuss scenarios where BMIs can augment our capabilities, from car driving to sports and human-robot interaction.

Motion Tracking for VR, AR, and Smart Appliances

​

Video games, Virtual Reality (VR), Augmented Reality (AR), and Smart appliances (e.g., smart TVs and drones) all call for a new way for users to interact and control them. Motivated by this observation, we have developed a series of novel motion tracking technologies using acoustic signals. A unique feature of our approach is that it can achieve mm-level tracking accuracy on smartphones without special hardware. We further develop a few interesting applications on top of our motion tracking technology.
