The application of ultrasound waves which pose negative effect on body tissues. One is thermal effect where the ultrasound waves heat body tissues up. Another is cavitations, where small bubble of gas are released upon exposure to extreme negative pressure. Besides, high decibels of ultrasound waves would injured hearing. Recommendation: 2. The need for a proper charging system without having to remove the bracelet from the patient The bracelet shouldn't be removed at all from the patient even for charging because of the unforeseen heart attack. Recommendation: A mini power bank should be included with the bracelet as a set. When it's time to charge the bracelet, it can be connected to the mini power bank via cable. 3. Allergies of certain patients towards plastic The strap of our device would be composed of plastic material like polyurethane in order to make it durable and provide comfort to the patient. However, certain people are allergy towards plastic. Recommendation: To be more flexible, we could also another version of this device, in which the strap is composed of latex. Experimental Design of Own Device -testing: people with heart conditions Select people that have a known risk for heart attack How many?: (70 million people with high blood pressure) 1000 people 10 hospitals~ Throughout the US People wear the device all the time and see how successful it is ^detect heart attacks and notification Did it detect the heart attack accurately or not Detect blood pressure with two devices on same patient (blood pressure meter) ^paired T Test Detect blood flow with a larger model ^paired T Test Detect Heart Rate with finger heart rate sensor compared to wrist/patch heart rate sensor ^paired T test As a patient goes to the hospital, their physical health will be measured on both devices
