A Miniature Low-power Adjustable Constant-voltage Deep Brain Stimulation Device

摘要：

　　This paper presents a lightweight portable low power deep brain stimulation device for laboratory animals.The device can be mounted directly on the animal,and can deliver simulation pulses for long term clinical trials with minimal disturbance.The device produces monophasic stimulation pulses with duration of 90μs at a frequency of 130Hz.The amplitude of these regulated pulses is adjustable from 20mV to 1.1V.The current draw is at a minimum of 200μA at 20mV and a maximum of 236μA at 1.1V when a 1kΩ resistor is used to model the brain tissue of the animal.From these values it can be projected that the device could theoretically last up to 49 days on a 235mAh button battery.
