Wireless Ear EEG to Monitor Drowsiness
These results demonstrate for the first time that dry, 3D printed, user-generic electrodes can be used with wireless electronics to rapidly prototype wearable systems, which achieve comparable average accuracy (>90%) to existing state-of-the-art in-ear and scalp ExG systems that utilize wet electrodes and wired, benchtop electronics.
A Sparse Sampling Sensor Front-end IC for Low Power Continuous SpO$_2$ \& HR Monitoring
Photoplethysmography (PPG) is an attractive method to acquire vital signs such as heart rate and blood oxygenation and is frequently used in clinical and at-home settings.
Phased array beamforming methods for powering biomedical ultrasonic implants
Millimeter-scale implants using ultrasound for power and communication have been proposed for a range of deep-tissue applications, including neural recording and stimulation.
SOUL: An Energy-Efficient Unsupervised Online Learning Seizure Detection Classifier
Implantable devices that record neural activity and detect seizures have been adopted to issue warnings or trigger neurostimulation to suppress epileptic seizures.
Memory-Efficient, Limb Position-Aware Hand Gesture Recognition using Hyperdimensional Computing
Electromyogram (EMG) pattern recognition can be used to classify hand gestures and movements for human-machine interface and prosthetics applications, but it often faces reliability issues resulting from limb position change.
