Batteries can threaten our health and safety. Most forms still have problems of reliability, price, life, weight, size or working cold. Fast charging and discharging and even deep discharge can still be inadequate for many applications. Improving the battery is proving very useful but other workarounds are increasingly attractive, feasible and affordable. Increasingly, we can manage with less or no battery and that is the subject of this webinar. Learn how specification compromises, energy harvesting and supercapacitors are increasingly attractive. For example, the pen in your phone is a battery-free circuit now. Planning has begun for 6G Communications which promises to operate user devices without power. No more cutting you open to change the battery in the implant on your heart. There are four routes to battery elimination achieving that. Understand why multi-mode harvesting and new forms such as harvesting infrasound and using triboelectrics look promising. Learn applications for the newest supercapacitor variants with the best of both worlds between supercapacitors and batteries. What, why, where, when, who? Best practice?
