E-Eye: Hidden E-device Recognition Through mmWave Nonlinear Effects

Hidden e-devices can be dangerous (e.g., disguised bombs & evasdropping).
Current solutions: cost-inefficient & invasive (e.g., x-ray imaging).
Low-cost & portable mmWave probe inducing the nonlinear response of e-devices.
Fine-grained signal analysis for extracting the e-devices' identitities.
Well-designed evaluation with various attack schemes.

SITUG: Sensor-equipped Insole Based TUG Analysis

Falls are the leading cause of injuries in older population.
TUG: A balance assessment widely used to estimate fall risk.
Current TUG systems: bulky & unhandy (e.g., multi sensor attachments).
Wearable sensor-embeded insole for data sampling.
User-friendly smartphone app (i.e., real-time instructions & reports).
Competent TUG data analysis in cloud server.

mRehab: A Rehabilitation System Powered by 3D-printing Augmented Smartphone

Impairments following stroke is one of the leading causes of disability.
Patients have low adherence on at-home rehab exercise programs.
Current situations: static, tedious setup & lack of informatic reports.
mRehab [Project website]:
ADL orientated: Activities of Daily Living is great for functional recovery.
Smartphone: Real-time visual, audio rehab instructions and reports.
3D-printing: Reshape the rigid form of smartphone for ADL simulation.
Smartphone + 3D-printing: Customizable, portable & informatic rehab tools.

Batteryfree & Wireless Personal UV Exposure Tracker

UV exposure is strongly related to a variety of ocular and skin diseases.
Existing exposure trackers target at unobtrusive and in-situ monitoring.
The constraint is the limitation of battery capacity.
Batteryfree is challenging due to the power-hungry sensors & wireless transit.
The first self-powered prototype for wireless UV exposure tracking.

Inclusive User Interface via Respiration Analysis

Keyboards and mouses are not applicable for users with disabilities.
Solutions are lack of stability &/ privacy-preservation.
- (e.g., brain-computer interface & eye movements)
Respiration is a universal, inconspicuous & controllable physiology feature.
This study presents a proof-of-concept respiration-based inclusive interface.
A RF radar is deployed for respiratory sensing in a secure manner.

Customizable Framework for Mobile Health Studies

Smart health is increasingly utilized in medical studies.
Researchers struggle with having the proper smart health applications.
Customizable framework:
Researchers customize applications by designing simple study packages.
A study package contains common-use files (Json & CSV).
The framework auto configures the packages into the desired apps.
