A double-coil wireless passive digital electromagnetic handwriting pen comprises an electromagnetic resonance wireless power supply module, a pressure-sensitive information receiving and transmittingmodule and a control module. The electromagnetic resonance wireless power supply module is arranged to utilize a first coil and a handwriting screen antenna module to carry out electromagnetic resonance so as to obtain electromagnetic energy and convert the electromagnetic energy into electric energy used for supplying power. The pressure-sensitive information receiving and transmitting module isarranged to receive the switching control signal and control the second coil to work in a pressure-sensitive detection state for collecting the pressure-sensitive signal or a data transmitting state for transmitting a data signal according to the switching control signal. The control module is connected with the pressure-sensitive information receiving and transmitting module, and the control module is arranged to provide the switching control signal for the pressure-sensitive information receiving and transmitting module, receive and process the pressure-sensitive signal and output the data signal. The passive inductive pen can be charged and used for writing at the same time.
