顱內高壓發生的原因主要是受到外傷出血、腦脊液分泌過多、吸收障礙或是先天性導水管狹窄等情況引起。一旦出現顱內壓超過20mmHg的情況，須立即進行腦脊液引流手術，否則將會對大腦造成永久性傷害，尤其出血性顱內高壓在30天內的死亡率高達50%。
研究指出顱內高壓最有效的治療方式為腦室外引流(External Ventricular Drain，EVD)，因其能夠直接量測腦室內的壓力數值和對腦室內多餘的腦脊液進行有效引流。本研究主旨為將無線壓力感測器結合EVD系統量測顱內壓力數值，改善ICU病房的複雜性且盡可能減少EVD手術的照護流程。本研究首先以簡易設計的液面下壓力將感測器數值進行補償，後續結合製作而成的大腦模型，設計出兩種主要顱內高壓的形式。不斷的驗證不同大腦模型的合理性並和無線壓力感測器所量測出來的數值做比較，成功的將無線壓力感測器數值的誤差控制在美國國家標準協會（American National Standards Institute，ANSI）對於顱內壓監測系統的規範，顱內壓0-20mmHg範圍內±2mmHg，>20mmHg在10%誤差內。

Intracranial hypertension is mainly caused by traumatic hemorrhage, excessive secretion of cerebrospinal fluid, absorption disorders, or congenital aqueductal stenosis. Once intracranial pressure exceeds 20mmHg, cerebrospinal fluid must be drained immediately. Otherwise, permanent damage to the brain will be caused, especially hemorrhagic intracranial hypertension, which can lead to a 50% mortality rate within 30 days.
Studies have shown that the most effective treatment mode of intracranial hypertension is External Ventricular Drain (EVD), which directly measures the ventricular pressure and effectively drains excess cerebrospinal fluid in the ventricle. The purpose of this study was to measure intracranial pressure with a wireless pressure sensor combined with an EVD system to improve the complexity of the ICU ward and minimize the care flow of EVD surgery. In this study, the values of the sensor were firstly compensated by the simple design of the pressure below the liquid level, and then two main forms of intracranial hypertension were designed by combining the brain model made by the deployment. The rationality of different brain models was constantly verified and compared with the values measured by the wireless pressure sensor. The error of the wireless pressure sensor value is successfully controlled within the American National Standards Institute (ANSI) specification for intracranial pressure monitoring systems. The intracranial pressure is ±2mmHg within the range of 0-20mmHg, and the error of >20mmHg is within 10%.
