Innovative Wearable Device by Northwestern University Measures Blood Pressure Without Invasiveness

Are you looking for a way to keep track of your blood pressure without having to get it checked with an invasive medical procedure? Northwestern University has come up with an innovative solution.

The researchers at Northwestern University have recently developed a patent, US20230225623A1, that provides a system and method for measuring blood pressure without inserting anything into the body. Their solution involves using a wearable device with two sensors that detect signals that indicate changes in blood volume and cardiac motion.

This patent has the potential to revolutionize the way we monitor our health. The two sensors used to detect the signals are placed on the skin surface of the subject and detect the changes when the heart pumps and blood flows through the body. The signals detected by the sensors then go to a processor that uses the information to calculate a blood pressure measurement.

The technology behind this patent is pulse transit time (PTT). PTT is the time it takes for the heart's pulse to travel from the heart to a certain point in the body. The wearable device with two sensors measures the PTT to calculate the blood pressure. This method is non-invasive and hence does not require any needles or other intrusive procedures.

The benefit of this technology is that it is not only non-invasive, but also more accurate than traditional methods. In traditional methods, a cuff is placed on the arm and inflated to measure blood pressure. But this method has some drawbacks as it gives inaccurate readings if the cuff is not placed correctly. The new technology eliminates this issue and gives more accurate readings.

Another advantage of this new technology is that it is easy to use. The wearable device is easy to put on and take off. It is also very convenient to carry around as the sensors are lightweight and small. The device is also water-resistant, so you can wear it in the shower or while swimming.

This technology has a lot of potential applications, ranging from monitoring a patient's blood pressure at home to using it in a clinical setting. It could be used to monitor a patient's blood pressure over a long period of time, which would help doctors identify any fluctuations or abnormalities in the patient's blood pressure. It could also be used in sports and fitness settings to keep track of a person's heart rate and blood pressure.

The fact that this technology is a patent means that there is no certainty as to whether it will come to the market or not. Northwestern University has done some very promising research on this technology, and it might be used in the near future to monitor blood pressure without any invasiveness.

It is exciting to think of the potential applications of this technology and how it could help us keep track of our health. The researchers at Northwestern University have done a great job in developing this patent, and we hope that their work will be put to good use in the near future.
