Development of microconnector with an automatic connecting/disconnecting mechanism

Abstract

We developed microconnectors with an automatic connecting/disconnecting mechanism using magnetic force. The electrical terminals were designed to minimize the friction force during connection/disconnection and were fabricated using a deep X-ray lithography technique. The diameter and thickness of the microconnector are 2.5 mm and 2 mm, respectively. We con®rmed the electrical connection at 160 mA/line and the automatic connection/disconnection at a distance of 600 lm between opposing microconnectors.
