We present CapBand, a battery-free hand gesture recognition wearable in the form of wristband. The key challenges creating such system are (1) to sense useful gestures at ultra-low power so that device can be powered by limited energy harvestable from surrounding environment and (2) make work reliably without requiring training every time user puts on successive capacitance sensing, an sensing technique, capture small skin deformations due muscle tendon movements user's wrist, which...
Frequent blood pressure (BP) assessment is key to the diagnosis and treatment of many severe diseases, such as heart failure, kidney hypertension, hemodialysis. Current "gold-standard'' BP measurement techniques require complete blockage flow, which causes discomfort disruption normal activity when done repetitively frequently. Unfortunately, patients with hypertension or hemodialysis often have get their measured every 15 minutes for a duration 4-5 hours more. The wearing cumbersome limited...
Diabetes affects millions in the US, causing elevated blood glucose levels that could lead to complications like kidney failure and heart disease. Recent development of continuous monitors has enabled a minimally invasive option, but discomfort social factors highlight need for noninvasive alternatives diabetes management. We propose portable sensing system based on glucose's optical activity property which rotates linearly polarized light depending its concentration level. To enable form...
Sindbis virus (SV) is an alphavirus that causes acute encephalomyelitis in mice. The outcome determined by the strain of and age genetic background host. mortality rates after infection with NSV, a neurovirulent SV, were as follows v: 81% (17 21) BALB/cJ mice; 20% (4 20) BALB/cByJ mice (P < 0.001); 100% A/J, C57BL/6J, SJL, DBA 79% (11 14) immunodeficient scid/CB17 Treatment Nomega-nitro-L-arginine methyl ester (L-NAME), nitric oxide synthetase (NOS) inhibitor, increased to 0.05) NSV-infected...
This paper explores a new wearable system, called TYTH, that enables novel form of human computer interaction based on the relative location and between user's tongue teeth. TYTH allows its user to interact with computing system by tapping their is analogous using finger type keypad except substitutes for teeth keyboard. We study neurological anatomical structures design so obtrusiveness social awkwardness caused minimized while maximizing accuracy sensing sensitivity. From behind ears,...
Microsleep, caused by sleep deprivation, apnea, and narcolepsy, costs the U.S.'s economy more than $411 billion/year because of work performance reduction, injuries, traffic accidents. Mitigating microsleep's consequences require an unobtrusive, reliable, socially acceptable microsleep detection solution throughout day, every day. Unfortunately, existing solutions do not meet these requirements.
Manual clinical scoring systems are the current standard used for acute asthma care pathways. No automated system exists that assesses disease severity, time course, and treatment impact in pediatric severe exacerbations.machine learning applied to continuous vital sign data could provide a novel pediatric-automated respiratory score (pARS) by using manual (PAS) as standard.Continuous monitoring (heart rate, pulse oximetry) were merged with health record including provider-determined PAS...
Accurately measuring and monitoring patient's blood oxygen level plays a critical role in today's clinical diagnosis healthcare practices. Existing techniques however either require dedicated hardware or produce inaccurate measurements. To fill this gap, we propose phone-based estimation system, called PhO2, using camera flashlight functions that are readily available on off-the-shelf smart phones. Since phone's not made for purpose, utilizing them poses many challenges. We introduce...
Face touch is an unconscious human habit. Frequent touching of sensitive/mucosal facial zones (eyes, nose, and mouth) increases health risks by passing pathogens into the body spreading diseases. Furthermore, accurate monitoring face critical for behavioral intervention. Existing systems only capture objects approaching face, rather than detecting actual touches. As such, these are prone to false positives upon hand or object movement in proximity one's (e.g., picking up a phone). We present...
We propose a compact noninvasive glucose monitoring system using polarized light, where user simply needs to place her palm on the device for measuring current concentration level. The primary innovation of our is ability minimize light scattering from skin and extract weak changes in polarization estimate concentration, all low-cost hardware. Our exploits multiple wavelengths intensity levels mitigate effect diversity confounding factors (e.g., collagen elastin dermis). It then infers...
We report an autochthonous human case of tickborne encephalitis (TBE) in the Bordeaux area, southwestern France. The patient was a farmer who had severe encephalomyelitis. ELISA and neutralization assay serum cerebrospinal fluid established diagnosis. This potential new endemic focus for TBE virus should be further investigated.
Patients with respiratory diseases require frequent and accurate blood oxygen level monitoring. Existing techniques, however, either need a dedicated hardware or fail to predict low saturation levels. To fill in this gap, we propose phone-based estimation system, called PhO 2 , using camera flashlight functions that are readily available on today’s off-the-shelf smartphones. Since the phone’s were not made for purpose, utilizing them poses many difficulties. We introduce cost-effective...
In this work, we design a wearable-form hand gesture recognition system using capacitive sensing technique. Our proposed includes 3D printed wristband, sensors arrays in flexible circuit board, low-cost micro-controller unit and wireless communication module (BLE). particular, the wristband manipulates changes capacitance from multiple to recognize detect users' gestures. The software stack translates detected gestures into control command for application layer, together with an...
While the global healthcare market of wearable devices has been growing significantly in recent years and is predicted to reach $60 billion by 2028, many important applications such as seizure monitoring, drowsiness detection, etc. have not deployed due limited battery lifetime, slow response rate, inadequate biosignal quality.
Drones have carried weapons, drugs, explosives and illegal packages in the recent past, raising strong concerns from public authorities. While existing drone monitoring systems only focus on detecting presence, localizing or fingerprinting drone, there is a lack of solution for estimating additional load by drone. In this paper, we present novel passive RF system, namely DroneScale, to monitor wireless signals transmitted commercial drones then confirm their models loads. Our key technical...
Abstract Difficulty falling asleep is one of the typical insomnia symptoms. However, intervention therapies available nowadays, ranging from pharmaceutical to hi-tech tailored solutions, remain ineffective due their lack precise real-time sleep tracking, in-time feedback on therapies, and an ability keep people during night. This paper aims enhance efficacy such by proposing a novel aid system that can sense multiple physiological signals continuously simultaneously control auditory...

Over 50 million people undergo surgeries each year in the United States, with over 70% of them filling opioid prescriptions within one week surgery. Due to highly addictive nature these opiates, a post-surgical window is crucial time for pain management ensure accurate prescription opioids. Drug nowadays relies primarily on self-reported levels determine frequency and dosage drug. Patient self-reports are, however, influenced by subjective tolerance, memories past painful episodes, current...
Frequent blood pressure monitoring is the key to diagnosis and treatments of many severe diseases. However, conventional ambulatory methods require patients carry a (BP) device for 24 h conduct measurement every 10--15 min. Despite their extensive usage, wearing wrist/arm-based BP long time has significant impact on users' daily activities. To address problem, we developed eBP measure from inside user's ear aiming minimize measurement's normal activities although maximizing its comfort...
