電刺激療法一直以來在醫學、神經學裡扮演著一個重要的角色，應用在腦電刺激、肌電刺激抑或是耳電刺激，其各自存在有相對應處理的電刺激方法，如經顱直流電刺激術、迷走神經透皮電刺激術，其各自又對應於不同的病症，如帕金森氏症、失語症，癲癇，到耳鳴、偏頭痛或疼痛抑制等，都能見到電刺激療法的身影。本系統網羅醫學領域、電機領域之相關研究，在常見研究需求與實際層面限制之間斟酌，整合開發了一套多研究應用導向之可攜式電刺激系統，並依此系統，進一步特化開發出一套耳部迷走神經透皮電刺激穿戴式裝置，驗證此系統之有效性與實用性。
在多研究應用導向的電刺激系統中可分為前端硬體電路系統、韌體系統、多研究應用導向之使用者介面(智慧型裝置應用程式)。其中前端硬體電路系統，包含了高電壓程式可控之定電流系統、數位訊號控制單元與電流電壓監控單元，依照不同控制指令輸出相對應之需求電流；韌體系統主要為一個具藍芽傳輸功能之微控制器，依使用者介面控制前端電路系統；使用者介面方面，針對多研究應用特化了兩種上述提及的電刺激功能，並進一步又在解析度上提供兩種選擇，以提供不同研究導向與功耗優化。

From then till now, electrical stimulation treatment plays an important role in the medical technology and neurology. It can be used to provide stimulation on brain, muscle or auricle. The stimulation methods and targets are different. For instance, transcranial direct current stimulation on head or transcutaneous vagus nerve stimulation on auricle. In addition, the aim of these methods are also different, like Parkinson’s disease, aphasia, epilepsy tinnitus, migraine or pain suppression. Based on the background and collection of electrical and medical papers which are relate to this topic, this paper implemented a multiple research-oriented portable stimulation system. The system is integrated under the balance between common specification and restriction of reality. Moreover, a wearable transcutaneous auricular vagus nerve stimulator is implemented. It is based on the multiple research-oriented portable stimulation system. The realization is also complete to verify the practicality and validity of the portable stimulation system.
The multiple research-oriented portable stimulation system is integrated by three parts, including a hardware for wearable stimulation, a firmware for communication and control, and a user interface on a smart device specified for multiple research-oriented. The hardware is integrated by a controllable constant current with high voltage source system, a digital control unit and a monitor unit for current and voltage. The given stimulation is dependent on the control from firmware. The firmware is a microcontroller unit equipped with Bluetooth 5.0 transmission. It acts as a bridge to control hardware system by the operation code from user interface. The user interface is designed for two different-type stimulations mentioned above. Moreover, it provides two different classes to achieve purpose of multiple research-oriented and improvement on power consumption.
