This paper presents a vibration energy harvesting concept where a piezocomposite beam submerged in an internal flow is used to harvest flow energy aimed to enable a self-powered low-cost blood pressure measurement device. First, several commercial semi-automatic and automatic blood pressure monitors are examined for their power consumption. An experimental apparatus based on a piezocomposite cantilever beam submerged in a converging-diverging channel is developed. The voltage output of the prototype flow energy harvester is characterized experimentally. Results from preliminary experiments showed an average voltage output of 0.5 Vrms when the apparatus is actuated by hand inflation using a standard bulb. The experiments with steady flow input revealed complex and interesting aeroelastic interactions leading to large sustained periodic deformations and power output.
