N2 - This paper presents a new setup and method of measuring pulse transit time (PTT) using seismocardiographic data from a MEMS accelerometer and acoustic recordings from a commercial microphone placed inside the ear. A DSP system is designed and implemented in MATLAB, and experimentally tested on 5 healthy adult subjects at rest. Failure conditions are also examined to evaluate the robustness of the system. Our results suggest that the proposed technique could be a highly-relevant method for PTT measurements, which could be further translated into blood pressure (BP) values.
