Our vision: Using radar technology to enable touch-free and continuous vital sign monitoring for stationary hospital patients, home care, follow-up care, and infant observation.

Continuous monitoring of vital signs is a crucial task not only in hospitals. Electrocardiography (ECG) and photoplethysmography (PPG) have been established as state-of-the-art devices to monitor the heart rate of patients. It is important to observe the cardiac activity as it allows doctors and nurses to immediately react to sudden changes of the physical condition as every second counts in emergency situations.

However, all available technologies for continuous observation of vital signs have the common disadvantage that they necessitate direct and permanent contact with the skin. Since patients are therefore bound to diagnostic machines by ...

Research Abstract:

Continuous monitoring of the central blood pressure waveform from deeply embedded vessels such as the carotid artery and jugular vein has clinical value for the prediction of all-cause cardiovascular mortality. However, existing non-invasive approaches, including photoplethysmography and tonometry, only enable access to the superficial peripheral vasculature. Although current ultrasonic technologies allow non-invasive deep tissue observation, unstable coupling with the tissue surface resulting from the bulkiness and rigidity of conventional ultrasound probes introduces usability constraints. Here, we describe the design and operation of an ultrasonic device that is conformal to the skin and capable of capturing blood pressure waveforms at deeply embedded arterial and venous sites. The wearable device is ultrathin (240 μm) and stretchable (with strains up to ...

Transplantable unions of living cells and electronic circuits interfaced with body parts, will be used to test, measure, monitor, control, repair, replace, or assist the functioality of body parts.

Ordinary cells and stem cells are deposited upon, grown, attached to, united, and coupled with non-rejectable electronic circuits, sensors, radio tranceivers, optical, electro-optical, and/or computer systems, to form new transplantable unions. Cells are 3D-printed, deposited, dipensed, painted, sprayed, air-brushed, injected, squirted, spritzed, or delivered by other means upon circuits, or optical systems.

Circuits can be manufactred by ordinary methods, 3D-printing, or other means. Printed circuits, ICs, other circuits, and optical systems are ordinary or are designed to adaptively couple with cells by having surfaces, undercuts, ridges, depressions, interstitial spaces, bumps, ...

The cranes that are used in hydrotherapy, most of all in swimming pools, are used to move up and down patients with some disabilities. Many of these cranes are hydraulic and maneuvered manually; only a few are semi-automatic and use an electric actuator. The problem is that its use is very rudimentary and not very precise; since it would also be necessary to have two therapists to be able to lower the patient to the pool, which is also very tedious.

One of the best ways to optimize this process and make it easier, safer and more pleasant is using an automatic crane that does the whole process of raising and lowering the patient to the pool. The crane ...

Concern in contemporary dental practice because of the underlying possibility of transmission of blood-borne viruses. The estimated transmission rates for hepatitis B (HBV) to non-vaccinated recipients, hepatitis C (HCV) and human immunodeficiency virus (HIV) after a needlestick injury from a dental needle are 6-30%, 2.7-10% and 0.1-0.3% respectively, because of the rise in HCV positive.

Application: Dental practice

Issue: Sharp needle injuries in dental practice

Injuries from dental syringe needle recapping remain a concern in contemporary dental practice because of the underlying possibility of transmission of blood-borne viruses*.

The estimated transmission rate for hepatitis B (HBV) to non-vaccinated recipients, hepatitis C (HIV) and human immunodeficiency virus ...

"CATCH" is a low cost, user-friendly, self-testing device which detects HIV. In emerging nations, this promotes individuals (who are prevented from travelling for miles to see a physician) to test for HIV at home.

Unfortunately, many individuals lack schooling due to a multitude of variables in emerging nations (including gender inequality, lack of infrastructure, poverty - the list goes on). CATCH is highly intuitive and anyone can use it. It is intended to do all the user's thinking and operates in three simple measures:
1. Sliding the disinfectant sleeve over the finger
2. Push down on the pipette/needle top
3. Press the button to see the result

This simple device has the potential to save millions of lives due ...

Traditionally, orthopedic surgeons have relied upon surgical screws to stabilize bone fractures. However, these screws often need to be removed due to pain and inadequate performances, causing surgical device removal surgeries to account for over 30% of all planned orthopedic surgeries. Screws have protruding heads that make them prone to catching on nearby muscle and nervous tissue, causing immense pain for patients. Additionally, screws occupy a large portion of the medullary canal, impeding bone tissue healing. Screws also often “back out”, or loosen, which requires costly followup surgery to redo them. These concerns would be resolved with our product, FastenPro.

FastenPro fastens a wire perpendicular to the fracture, through the bone, to be secured on either end by stainless ...

The Smart Life Guard Pajamas (SLGP) can be useful in two main cases:

1) In the case of Sudden Cardiac Arrest – A lot of adult people suffer from cardiac problems, which can cause Cardiac Arrest. Because of this reason plenty of people die during sleep, without any chance of medical help.
2) In the case of Sudden Infant Death Syndrome (SIDS) – sudden unexpected death of a child in the age until three years.

Depending on the cases the SLGP can be designed in the needed sizes.

It can be designed with two levels of protection:

1) Heart stop alert – it senses the heart pulse rate and when absence of heart beats is registered – it reacts ...

Shower Belt is the world's first drowning and scalding prevention device for use in the shower. It uses your own body weight to stop the flow of water should you fall. I designed Shower Belt after the sudden and tragic loss of my friend Natalie Fryzak. Natalie succumbed to drowning as a result of an Epileptic seizure while in the bathroom. 50 million people suffer from Epilepsy world wide. With a 20% higher chance of drowning then non-effected people, it is reported 88 people a day will drown in and around the home. You can see this device is long overdue! Shower Belt also protects our elderly. With many aging in place at home retirement is why the assistive ...

Parkinsonism is a group of chronic neurological disorders characterized by progressive loss of motor function resulting from the degeneration of neurons in the area of the brain that controls voluntary movement. All types of Parkinsonism are characterized by four main signs, including tremors of resting muscles, particularly of the hands; muscular rigidity of the arms, legs, and neck; difficulty in initiating movement (bradykinesia); and postural instability. A variety of other features may accompany these characteristics, including a lack of facial expression (known as “masked face”), difficulty in swallowing or speaking, loss of balance, a shuffling gait, depression, and dementia. Peoples who suffer from Parkinsonism cannot drink fluid without any assistance and it is impossible for them to do it ...
