AI Technical Summary

Benefits of technology

This patented technology describes a new type of small battery that uses tiny metal wires attached to each other instead of traditional batteries made up of large particles or liquid droplets. These miniature metals are very sensitive but they cannot be directly connected into electronic circuits due to their high resistance compared to conventional materials like silicon dioxide (SiO2). To overcome this problem, these minute metallic wire networks have been developed called nanoelectronics. By combining them together, there will become more efficient ways to measure molecules at low concentrations without being affected by external factors such as temperature changes or humidity levels. Additionally, the electric current generated through the nanoparallel connections between individual metallized wires helps create stable voltages over time. Overall, this innovative design allows for easy manufacturing and replacement of expensive components within smaller devices.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the efficiency and reliance of detecting small quantities of substances like biomarkers through chemical reactions involving elec trocatalysis systems. Current methods involve complex structures requiring expensive instrumentation and complicated operations, limiting usages. There exists a new approach called ultrasound elecrocence analysis (ECA) where sensitive areas and reaction fields are create within the elecrosis layer without modifying them themselves during manufacturing processes.
