Hypertension is the cause of several severe health conditions like heart attack, stroke, and heart failure. Pre-hypertension, mild hypertension, moderate hypertension, and severe hypertension are the four stages of hypertension. Currently, different types of medications like Thiazide diuretics, Angiotensin-converting enzyme (ACE) inhibitors, Angiotensin II receptor blockers (ARBs) are available in the market to lower the blood pressure. However, there are many side effects of the medications which have increased the demand of non-invasive techniques to lower the blood pressure. The existing non-invasive techniques are not effective for immediate results. Thus, we have designed a non-invasive bioelectronic blood pressure cuff to reduce the blood pressure. The device consists of silicone rubber ring which was the housing of the TENS electrodes and TENS device. TENS device and TENS electrodes were connected via copper wire. The silicone rubber ring was fabricated with the help of ABS plastic mold by using injecting molding technique. After the fabrication of the device, all the components were assembled within the ring. Two separate prototypes were built for animal model and human model. The difference between the two prototypes were the position of the TENS device and the size of the ring. The prototype of the animal model was built to test the device in animals before testing it in humans. The partial testing of the device showed some convincing results that the device was working however, the conclusion could not yet be done due to COVID- 19 outbreak.
