A deep brain stimulator (DBS), also known as a neuro-stimulator, is a medical device that uses electrical stimulation to treat neurological disorders such as Parkinson's disease, essential tremor, dystonia, and obsessive-compulsive disorder (OCD). The DBS is typically implanted under the skin near the collarbone or in the abdomen, and connected to a thin wire, or lead, that runs under the skin to the targeted area of the brain as shown in Figure 1.

Electronic devices power our world and allow us to communicate. In all applications requiring signal integrity and accurate power amplification, blocking capacitors are used to provide clean waveforms and correctly amplified voltages.

Electronic devices provide the tools we need to power the world. From cell phones to modern vehicles to scientific equipment to the appliances in our homes, we rely on electronics to improve and even lengthen our lives. All electronics depend on clean power, and the bypass capacitor is crucial in ensuring devices safely meet their power specifications.

To protect people and critical equipment, military-grade electronic devices must be designed to function reliably while operating in incredibly harsh environments. Therefore, instead of continuing to use traditional silicon semiconductors, in recent years, electronic device designers have started to use wide band-gap (WBG) materials such as silicon carbide (SiC) to develop the semiconductors required for military device power supplies. In general, WBG materials can operate at much higher voltages, have better thermal characteristics, and can perform switching at much higher frequencies. Therefore, SiC-based semiconductors provide superior performance compared to silicon, including higher power efficiency, higher switching frequency, and higher temperature resistance as shown in Figure 1.

From industrial to automotive to aerospace applications, power electronics are demanding higher capacitance in smaller packages. Therefore, to meet both capacitance demands and size requirements, electronic designers simply cannot continue to add more capacitors. While capacitor stacking is an option, many stacked assemblies are still quite large and stacking often introduces new failure modes, such as piezo electric cracking (Figure 1). 

As interest and adoption increase in the electric vehicle (EV) arena, associated technologies are advancing quickly. Batteries are becoming more powerful and charging infrastructure is increasingly robust and efficient. With all these advancements, EV batteries are good for more than powering cars on the road.
