一種將結合微芯片技術的微型電子刺激設備與傳統針刺技術，能夠治療慢性疼痛。

P-Stim是由Neuroscience治療公司(San Dimas, CA, USA)生產的，是一種經皮膚的耳狀電磁刺激設備，能夠進行耳部針刺治療。由微處理器控制，該設備能夠產生低頻電子脈沖，從耳部多點的棒狀傳遞給外周神經末端。這種刺激能夠導致內啡呔的釋放，從而產生止痛作用。

Electronic Device Applies Auricular Acupuncture
 
A miniaturized electro-stimulation device combines microchip technology with traditional acupuncture techniques to treat chronic pain.

P-Stim, manufactured by Neuroscience Therapy (San Dimas, CA, USA), is a percutaneous auricular electro-stimulation device that operates on the principle of auricular (ear) acupuncture. Micro-processor controlled, it generates a low-frequency electrical pulse that is transmitted to the peripheral nerve endings in the ear via a multi-point stylus. This stimulation results in the release of endorphins that have an analgesic, or pain-relieving, effect.
