Like all devices, there is always room for improvement. More efficient and advanced products are being created everyday. A few design flaws of the sensor is that it focuses on taking an external temperature reading which is much less accurate than an internal reading like the oral thermometer and when not being used, it shuts itself off. A possible solution to increase the effectiveness of the sensor would be to create a strap which would wrap around the torso that allows it to remain secure underneath the armpit and produce a more accurate reading.

Blood Pressure
The wrist and the upper arm are very different areas. In each of these areas, there are different arteries, tendons, and muscles, all of which have an effect on the blood pressure readings. The wrist is also very fragile and not as sturdy as the upper arm. The design flaw of the watch sensor is the area in which it is taking measurements and how sturdily it remains on the wrist. Being that it is automated, it appeals to the patient and the testing can be initiated easily and by one person. An improved design would be to have more straps that attach the watch to the wrist and an alert that tells you if you have high, low, or normal blood pressure.

The watch has a design flaw in that it is not able to efficiently obtain a reading from the wrist. An increased amount of securing straps and sensors would most likely solve this issue. These sensors would focus upon the bottom of the wrist where the brachial artery is located. In addition, the watch sensor should come with a micro-SD card that would allow for the storing of patient data. This can then be easily transferred to a computer and utilized accordingly.


Target Population and Need

The targeted population are; athletes and active people.

1. Athletes, useful during sports and practice sessions.

2. Active people, it comes in handy during normal routine workout and outdoor activity.

Device Design

Device name: iB.P

A designed athletic shoe that pumps up when activated by a mobile app to measure blood pressure and heart rate. The blood pressure is measured when the device is close to the arteries that’s on the foot. The arteries are called the Lateral and the medial plantar artery. This is convenient for athletes and active people to measure blood pressure and heart rate without having to use a traditional blood pressure monitor on the arm which can be bulky and uncomfortable during sports or exercise. It is easy to use and the user has access to it at all times by using a mobile application.
