| 摘要 |
Advances have been made in electrical stimulation for medical, diagnostic and therapeutic uses, including cutaneous uses and non-cutaneous uses (such as medical implant devices). The novel systems are based on a modulated continuous symmetric wave-form especially at a high-frequency (1 kHz-50,000 kHz), especially devices including a FPGA or ASCI chip. Such electrical systems finally make possible safe, miniaturized medical devices small enough to be hand-held or implantable. A high-frequency symmetric waveform is used to synthesize a low-frequency sine wave.
