    Abstract

    This paper presents a miniature light-weight closed-loop deep brain stimulation (DBS) device that delivers on-demand stimulation current pulses by monitoring and analysing local field potentials. The device includes monitoring and DBS units, each designed and fabricated on a separate small round circuit board. The closed-loop DBS device has been successfully validated by injecting a pre-recorded neural signal into its input, and collecting and analysing its output. The monitoring unit has an amplification gain of 113 dB in frequency range of 0.7-50 Hz. The DBS unit gives on-demand stimulation current pulses of duration 90 μs, frequency 130 Hz, and amplitude 200 μ. The total weight of the device including a 3V coin battery is 1.41 g. The diameter of the device is 11.4 mm. This portable head-mountable device is suitable for use in pre-clinical trials with small laboratory animals.
