Events-of-interest Capture Using Novel Body-worn Fully-passive Wireless sensors for S&CC

Link to NSF Smart and Connect Community (S&CC) Project

Patients with chronic illness require frequent and avoidable hospital visits. This project aims to develop a new class of battery-less, low-cost, disposable, wireless electronic patch sensors to monitor a variety of physiological signals and a custom smartphone app to monitor their health status and to elect to share their anonymized events-of-interest with their community towards a smart and connected community (S&CC). This will empower users, permit the community stakeholders to assess population health status, reduce the need for frequent hospital visits, and help identify potential individual and community actions to achieve improvement in health status. The project also involves the training of undergraduate and graduate students in interdisciplinary research activities on emerging technologies, and is expected to impact public and private sector efforts to improve healthcare.

Additive printed multilayer complex circuitry on flexible and disposable substrates

Inkjet printing is a relatively new technology for low temperature thin film depositions on planar substrates. The goal of this project is to develop a homogenous fabrication process using this technology for complex electronics circuitry towards low-cost and disposable body-worn electronic patches for healthcare applications. We have developed a novel technique for multilayer additive PCB development and utilized this thin film prototyping technology to develop our novel fully passive wireless sensors for physiological biosignal monitoring.

Fully-passive body-worn resistive wireless analog sensor (rWAPS)

Fully-passive wireless body-sensors pose viable solutions for unobtrusive monitoring of physiological signals at natural settings. We are developing a resistive transducer based wireless analog passive sensor (rWAPS) system that can collect various physiological signals while achieving smallest power requirement, fast response time, and extremely low cost disposable passive sensors. The passive sensor is composed of a loop antenna, a tuning capacitor, and a resistive transducer suitable for the type of physiological signals to be measured.

BRAINSens: Body-worn Reconfigurable Architecture of Integrated Network Sensors

The conventional EEG system consists of a driven-right-leg (DRL) circuit, which prohibits modularization of the system. We propose a Lego-like connectable fully reconfigurable architecture of wearable EEG that can be easily customized and deployed at naturalistic settings for collecting neurological data. The proposed scalable system is suitable for non-clinical settings with neurological patients. This cost-effective monitoring system with plug-and-play sensors is fast and easy to deploy. This system can incorporate any physiological sensor nodes like ECG, body temperature, pulse oximeter, etc.

Smart Drug Delivery System (DDS) by implantable chitosan microbeads with magnetic nanoparticles

The research group is developing a novel smart drug delivery system (DDS) based on biocompatible chitosan microfilm and microbeads for local delivery of encapsulated drugs released through external stimulations. It is envisioned that controllable DDS could facilitate maintaining drug concentration within prescribed therapeutic limits over desired duration or provide a burst release of drug when needed. Majority of DDS suffer from an uncontrollable diffusion profile, leading to passive drug release over time, or poor control of external or internal stimuli. We are developing a novel DDS platform based on chitosan embedded with magnetic nanoparticles (MNP) that is responsive to electric and magnetic stimulations.

NeuroMonitor Wearable Ambulatory EEG Device for Real-life Monitoring of Cognitive Loads

This research focuses on developing a wearable, miniature, ambulatory BCI to wirelessly capture brain signals in the form of electroencephalogram (EEG) in natural settings. Scalp EEG can monitor collective activities of neuronal firings in brain lobes as oscillatory waves that can be related to the mental states, cognitive loads, stimulations and perceptions. The prototyped NeuroMonitor device (3 revisions) was developed through careful hardware-software co-design to optimize size, power, portability and connectivity. The 2-channel system composes of 4-stage biopotential amplifier with active analog filtering, 16b ADC on PSoC3 micro-controller, along with other peripherals and power management circuits. The hardware is miniature (size: 2.2" x 0.8" x 0.36", weight: 41.8 gm) such that it can be concealed within a headband. The collected data can be wirelessly transmitted for on-line monitoring or stored on-board for offline analysis. Application areas are engagement monitoring of children with developmental delays, seizure detection and advisory system for epileptic patients, and Alzheimer's patients.
