Wearable smart electronic devices offer compelling capabilities of monitoring physiological parameters and the environment of the user with subsequent data analysis and their representation by immediate haptic feedback. This interdisciplinary PhD project builds on a collaboration between the IETR laboratory of CNRS and the IRISA laboratory of Inria / CNRS (RAINBOW team). Expertise of IETR covers complex radiating systems and radars, bioelectronics, and bioelectromagnetics. Research at IRISA focuses on the fields from computer and network architecture to artificial intelligence, including software engineering, distributed systems, and virtual reality.


Background and Motivation

Haptic feedback for wearables is receiving growing attention in consumer electronics, wireless biotelemetry of physiological parameters (e.g., heart and respiration rates, temperature, blood oxygen and glucose levels), and virtual reality applications. It is also a promising technology for assisting the visually impaired in navigating their surroundings, motion guidance for rehabilitation and physical training. A body-conformal wearable device can simultaneously monitor the vital signs and scan the environment using a radar to inform about surrounding objects and obstacles. The acquired information can be privately rendered to the user using an array of haptic actuators. Whereas both miniature biosensors and low-power radar technologies have sufficiently advanced in the recent years (allowing us to use off-the-shelf solutions), the flexible, robust, and reconfigurable on-body antenna arrays and corresponding RF circuits have not been proposed yet. In addition, the conformal antenna array has to be integrated with the array of haptic actuators while keeping the system light, compact, flexible, and robust to the environment (e.g., clothing, water, and small metallic objects).

The PhD candidate will work towards solving the aforementioned challenges. He/she will focus on the design of a body-conformal antenna array and RF circuit as well as their integration with of a wireless wearable haptic unit, which can be worn in a comfortable manner, including under clothing. Such device could be realized as, for instance, a flexible on-body patch that contains the antenna array and feeding network, haptic actuators (e.g., vibrotactile motors or skin stretch tactors), radar/sensor/communication units, and a rechargeable battery. To address the scientific and technical challenges, the successful candidate will have access to the interdisciplinary know-how of IETR in the field of complex radiating structures, radars, and bioelectronics as well as to the IRISA’s expertise in haptics and wearable interfaces. High-performance computing infrastructure and advanced numerical solvers will be used to handle computationally large multi-scale problems. State-of-the-art manufacturing and measurement facilities will help with the experimental characterization of the prototypes.

The final wireless system will be tested on tissue-equivalent models as well in vivo through established collaborations of IETR. Finally, the successful candidate will be expected to present results of the work in high-profile journals and conferences.
