We developed microconnectors with an automatic connecting/disconnecting mec
hanism using magnetic force. The electrical terminals were designed to mini
mize the friction force during connection/disconnection and were fabricated
using a deep X-ray lithography technique. The diameter and thickness of th
e microconnector are 2.5 mm and 2 mm, respectively. We confirmed the electr
ical connection at 160 mA/line and the automatic connection/disconnection a
t a distance of 600 mu m between opposing microconnectors.
