The capacitive stylus pen includes a power supply that is charged in a contactless manner, a coil provided at a position indicating part of the capacitive stylus pen, an electrode that penetrates through the coil and protrudes to form a tip part, and an alternating-current signal generating circuit that supplies an alternating-current signal to the electrode. During contactless charging, the coil is magnetically coupled to an external charge device that has a penholder shape, to thereby charge the power supply, which supplies power to the alternating-current signal generating circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive stylus pen","description":"A capacitive stylus pen that inputs an indicated position by capacitive coupling with a tablet is provided.
