Background:

• Deep brain stimulation (DBS) is a key neuromodulatory treatment for neurological and psychiatric conditions.
• Current DBS devices have limited waveform flexibility, hindering research into new stimulation mechanisms.
• Preclinical research requires advanced tools to test novel DBS paradigms.

Purpose of the Study:

• To address the need for flexible, low-power devices for preclinical DBS research.
• To develop a device capable of generating custom, biphasic stimulation waveforms.
• To facilitate the investigation of new DBS paradigms in animal models.

Main Methods:

• Design and development of a miniature, low-power, tetherless DBS device.
• Implementation of active charge balancing for safe operation.
• In-vitro testing of the device's custom waveform generation capabilities.

Main Results:

• The developed device offers high flexibility in waveform shape, frequency, pulse-width, and amplitude.
• It supports both traditional and advanced stimulation schemes, including non-rectangular and delayed feedback.
• The device enables the production of unique custom biphasic waveforms for preclinical studies.

Conclusions:

• The novel device overcomes limitations of existing preclinical DBS systems.
• It provides a versatile platform for exploring advanced DBS paradigms and mechanisms.
