An electronic device and a bioelectrical signal acquisition method are provided. The electronic device includes a rear housing, a plurality of first contact electrodes, and a plurality of second contact electrodes. A first contact area and a second contact area are distributed on the rear housing. The plurality of first contact electrodes/second contact electrodes are spaced on the rear housing respectively and electrically connected to each other. The first contact electrode and the second contact electrode are used for contacting with the skin respectively to form a bioelectrical signal acquisition circuit. At least one first contact electrode and at least one second contact electrode are distributed in the first contact area, and at least one first contact electrode and at least one second contact electrode are distributed in the second contact area.

Disclosed are an electronic device including a shell, a rotating frame, a guide limit mechanism, a sensor and a controller. The rotating frame is rotatably provided outside a part of the shell and configured to rotate to at least two gears relative to the shell. In response to that the rotating frame rotates to any one of the gears, the rotating frame is snap-fitted with the shell for positioning through a gear limit mechanism; and in response to that the rotating frame is rotated out of the gears by an external force, the rotating frame is released from the shell. The guide limit mechanism is configured to limit a rotation range of the rotating frame. The sensor is configured to sense a current rotation gear of the rotating frame and connected to the controller which is configured to control and perform a corresponding function according to the current rotation gear.

According to one embodiment, an electronic device includes a display panel, an antenna wiring substrate opposed to the display panel and including an antenna wiring line forming an antenna and a signal wiring line provided on the antenna wiring substrate and supplying a drive signal to the display panel.

A micro-electromechanical systems (MEMS) driving arrangement for an electronic device, the micro-electromechanical systems (MEMS) driving arrangement including a driven wheel; a driving actuation assembly for causing rotation of the driven wheel; an indicator assembly including an indicator; and a force absorbing assembly coupled intermediate the indicator assembly and the driven wheel; whereby a force acting upon the indicator assembly is absorbed by the force absorbing assembly so as to inhibit rotation of the driven wheel relative to the driving actuation assembly.

An electronic watch or clock with an electrostatic induction generator, wherein the electrostatic induction generator has a rotary weight able to rotate with respect to a housing, a rotary member able to rotate with respect to the housing, a counter substrate fastened to the housing, a charging film arranged at one of the rotary member and counter substrate, and a counter electrode arranged facing the charging film at the other, outputs electric power generated between the charging film and the counter electrode to a quartz movement, and provides a window part at one or more locations among the dial plate, housing, or outside casing to enable rotation of the rotary member or transmission of rotation to be visually confirmed.

A smart watch includes: a watch dial, a watch band, a monitoring apparatus, and a mechanical transmission apparatus; herein, sensors are set on both front and back surfaces of the watch dial; the watch band is made of hard material and has a multi-section structure; and beginning from a first section of watch band fixedly connected to the watch dial, each section of watch band is a hollow cavity structure that accommodates a next section of watch band; the monitoring apparatus is deployed within the watch dial; the mechanical transmission apparatus is set between the watch dial and the watch band, and is arranged to control extension or retraction of other sections of watch bands for automatically wearing or removal of the watch band. A smart watch automatic wearing method is further provided.
