醫(yī)療設(shè)計(jì)項(xiàng)目的傳感器解決方案

　　醫(yī)學(xué)不進(jìn)步科技，科技進(jìn)步醫(yī)學(xué)。這是在診斷、維修尤其如此，為阻斷和預(yù)防醫(yī)學(xué)監(jiān)測(cè)技術(shù)。傳感器技術(shù)，特別是基于微型化的改進(jìn)，尤其是MEMS領(lǐng)域的改進(jìn)，處于領(lǐng)先地位。MEMS芯片感知壓力，檢測(cè)運(yùn)動(dòng)（或缺乏），識(shí)別和測(cè)量力，泵液，控制流，等等。

　　傳感器被植入，通過切口進(jìn)入導(dǎo)管，或用于體腔；外部傳感器用于接觸體液和醫(yī)療器械。

　　今天的植入式傳感器非常小，重量輕，堅(jiān)固耐用，足以在很長一段時(shí)間內(nèi)使用。今天的醫(yī)療傳感器能夠區(qū)分行走、跑步和其他體力活動(dòng)。考慮到電源在某些設(shè)計(jì)中是一個(gè)問題，例如心臟起搏器，壓電式聚合物傳感器是微型的、可靠的，而且除了它們可以使用的環(huán)境之外，無需任何動(dòng)力。同樣，植入式傳感器也可以通過射頻技術(shù)以RF能量棒的形式在外部進(jìn)行供電。當(dāng)魔杖與天線和應(yīng)答器一起完成時(shí)，就被用來接近傳感器，傳感器醒來進(jìn)行測(cè)量，通過射頻鏈路將數(shù)據(jù)發(fā)送給棒，然后返回到睡眠模式。

　　Sensors placed by way of an incision， for example， attached to a catheter， are used to measure blood flow in the heart. These types of sensors are typically used in the short term， spanning minutes to hours.

　　Disposable silicon MEMS pressure sensors are used during the childbirth process to measure contraction frequency and pressure， and are removed after the baby is born. Disposable oral and rectal probes are used to measure body temperature.

　　Sensors that are exposed to fluids include disposable blood pressure sensors typically used during surgical procedures to monitor blood pressure. These sensors are replaced regularly. The sensor module is plugged into a monitor and logs all extracted information.
