The electroadhesion gripper has a diode by which the first and second spiral electrodes are connected to each other. Portions of the first and second spiral electrodes are connected in series by the diode, and an entirety of the connected portions of the first and second spiral electrodes has a perceptible inductivity. The gripper is driven with an alternating-current (AC) voltage and an occupation state and wear degree of the gripper can be determined during the AC voltage cycle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electroadhesion gripper for retaining workpieces","description":"An electroadhesion gripper for retaining workpieces includes a first spiral electrode having a plurality of turns and a second spiral electrode having a plurality of turns, the two spiral electrodes b","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9704734","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
