ELECTROMAGNETIC PEN
First Claim
1. An electromagnetic pen comprising:
- a pen core body;
an outer cladding surrounding the pen core body, the outer cladding made of electrically insulative material;
a plurality of elongated first conductors and a plurality of elongated second conductors alternately arranged on a circumferential surface of the outer cladding, each of the first conductors being electrically insulated from the corresponding neighboring second conductors;
an oscillator circuit configured to emit electromagnetic signals, the oscillator circuit comprising a voltage input port; and
a battery configured to provide power to the oscillator circuit, the battery comprising a voltage output port;
wherein, each of the first conductors is electrically coupled to the voltage output port of the battery, and each of the second conductors is electrically coupled to the voltage input port of the oscillator circuit; and
when the electromagnetic pen is held by a user, the first conductor is electrically connected to the second conductor via the user'"'"'s hand, causing the battery to provide voltage to the oscillator circuit through the voltage input port, and the oscillator circuit therefore emits electromagnetic signals.

Abstract
An electromagnetic pen includes a pen core body, an outer cladding surrounding the pen core body, an oscillator circuit and a battery. The outer cladding is made of insulative material. A number of elongated first conductors and a number of elongated second conductors are alternately arranged on a circumferential surface of the outer cladding, and each first conductor is electrically insulated from the corresponding neighboring second conductors. Each first conductor is electrically coupled to the battery, and each second conductor is electrically coupled to the oscillator circuit. When the electromagnetic pen is held by a user, the first conductor is electrically connected to the second conductor via the user'"'"'s hand, causing the battery to provide voltage to the oscillator circuit, and the oscillator circuit therefore emits electromagnetic signals.
