This project aims to architect and design an energy efficient stimulator circuit for peripheral nerve, and energy saving techniques such as adiabatic stimulation and/or charge recycling will be explored. An existing model is available within imec and can serve as a starting point for this project.
The peripheral nervous system (PNS) consists of the nerves
outside of the central nervous system (CNS) and connects the CNS to the organs,
limbs, and skin. It is a two directional pathway between CNS and internal
organs and hence can have powerful impact on the functionality of both.
Currently, interest in peripheral nerve stimulation is growing as an
alternative or a complement to pharmacological treatment, i.e., treatment with
medication, for applications such as epilepsy, pain, depression, and
inflammatory bowel disease.
One of the major challenges is reducing the power consumption and self-heating during the peripheral nerve stimulation. To minimize the power consumption, an adaptive power supply is beneficial. With this adaptive supply, the stimulator can provide only the minimum voltage that is needed for the load to keep the desired stimulation current (referred as “adiabatic” stimulation). This “adiabatic” feature saves power consumption and reduces self-heating during the stimulation. Furthermore, circuit techniques that can recycle some of the stimulated charges are also envisioned to further save power.
This project aims to develop an energy efficient stimulator circuit using the concepts mentioned above.
