“…The PESG is used in the quantitative analysis of pulse characteristics and can investigate changes in the shape of the pulse waves under varying contact pressure (Luo et al, 2012;Bae et al, 2013;Chu et al, 2014), while the contact force exerted by the other sensors can only be assessed subjectively by the operator.…”

“…Compared with other pulse signal acquisition systems, the proposed system had several advantages. Firstly, compared with the device proposed in the study [16], the pulse wave and the static force from the pressure device could be simultaneously collected by a MEMS pressure sensor array, which has a wide range, high sensitivity, and excellent repeatability. What's more, its quite mature technology ensured its good consistency.…”

“…The properties of the capacitive pressure transducer, such as sensitivity, repeatability, minimum element size, and temperature stability, are acceptable [9]. However, the pressure range is a little bit narrow, so additional pressure sensors are required to measure the static forces [16]. Besides, the structures of compound sensors like study [6,7] are involved; thus, it is easy to introduce interference from mechanical structures.…”

During pulse signal collection, width information of pulse waves is essential for the diagnosis of disease. However, currently used measuring instruments can only detect the amplitude while can’t acquire the width information. This paper proposed a novel wrist pulse signal acquisition system, which could realize simultaneous measurements of the width and amplitude of dynamic pulse waves under different static forces. A tailor-packaged micro-electro-mechanical system (MEMS) sensor array was employed to collect pulse signals, a conditioning circuit was designed to process the signals, and a customized algorithm was developed to compute the width. Experiments were carried out to validate the accuracy of the sensor array and system effectiveness. The results showed the system could acquire not only the amplitude of pulse wave but also the width of it. The system provided more information about pulse waves, which could help doctors make the diagnosis.

Electret condenser microphone as a traditional Chinese medicine arterial pulse sensor

Arterial pulse signal reading by a therapist in Traditional Chinese Medicine (TCM) requires considerable experience and thoroughness. The interpretation resulted by the therapist is very subjective. The objectivity of the device can be achieved by increasing the accuracy and the consistency of the reading in the range of 1-2 Hz. An electret condenser microphone (ECM) can be used as a pulse sensor in such device. This study reveals that ECM performs a number of advantages such as small-sized and inexpensive. Unfortunately, this ECM also picks up mechanical noises during direct contact with the subject. This study proposed soft silicon rubber as a medium between subjects and ECM. The technique was designed to enhance the mechanical coupling between the ECM and the source signal without affecting the signal source. The results show that the ECM could measure the signal of 0.5-10 Hz with the average accuracy of 99,47%.
