Cardiovascular diseases are the leading cause of death around the world. Non-invasive estimation of arterial parameters is significant in the early detection of cardiovascular diseases. In this work, we present an arterial compliance probe for calibration-free evaluation of carotid pulse pressure. This novel cuffless measurement technique uses dual magnetic(More)
— Controlled electrical stimulation of the retina can result in visual percepts in blind patients. In contrast to the over 100,000,000 photoreceptors in a healthy retina, even hundreds of pixels/electrodes of a retinal implant may restore low-resolution vision for unaided mobility and large print reading. We describe the real-time application of image(More)
— This paper presents a 4-channel wearable wireless neural recording system that consists of wireless head stage, receiver board, and user interface software. The wireless head stage is implemented using a custom designed font-end IC for bio potential amplification, filtering, and channel selection and a commercial analog FM transmitter chip.
