Precision horticulture is evolving due to scalable sensor deployment and machine learning integration. These advancements boost the operational efficiency of individual farms, balancing benefits analytics with autonomy requirements. However, given concerns that affect wide geographic regions (e.g., climate change), there a need apply models span farms. Federated Learning (FL) has emerged as potential solution. FL enables decentralized (ML) across different farms without sharing private data....
Demand for highly compliant mechanical sensors use in the fields of robotics and wearable electronics has been constantly rising recent times. Carbon based materials, especially, carbon nanotubes, have widely studied as a candidate piezoresistive sensing medium these devices due to their favorable structural morphology. In this paper three different namely black, graphene nano-platelets, multi-walled were utilized large stretch capable measuring stretches over 250%. These can be used robotic...
