Live Demonstration: Wireless Device for Pulse Wave Velocity Evaluation.

A low-cost wireless integrated device for evaluating pulse wave velocity (PWV) is presented in this live demonstration. The system consists of a base/charging station, two pen-shaped probes with high-precision MEMS micro force sensors on their tips. The ulnar and carotid arteries are the two probes pickup sites, exploiting Bluetooth to transmit pulse wave signals to the base/charging station. The signals and the respectively PWV value are displayed on a PC GUI concurrently. After adequate probe sterilization, visitors can observe an actual PWV measurement on a dedicated test subject or participate in a first-person arterial pulse evaluation on their carotid.
