The pen comprises a tip for writing on a screen of the touch sensitive device, a control circuit for emitting signals to the touch sensitive device, and a battery for providing electricity to the control circuit. The eraser includes an erasing circuit and a first end to combine with the pen, so that the erasing circuit electrically connects with the control circuit. The eraser includes a second end that is compressible, so that the control circuit can emit an erasing signal to the touch sensitive device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive stylus with eraser","description":"A capacitive stylus, as an inputting device of a touch sensitive device, comprises a pen and a detachable eraser.
