Embodiments of the invention provide a method, devices, and system for monitoring and sharing emotion-related data from one or more persons connected via the internet. An emotion monitoring device (EMD) measures physiological signals obtained from biosensors and computes emotion states relating to emotional arousal and valence. Various signal processing methods are employed to reduce artifact and improve the detection of emotional states. The EMD communicates the emotion data to an internet server via a wireless network. The internet server transmits the emotion data to other persons equipped with an EMD. Their emotion data similarly is obtained and shared with others. The networked emotion data can used to enrich online, community experiences such as games and social networks. An implementation of an EMD based on a smart phone enables emotion data to be monitored in wide area, mobile environment. The biosensors can be integrated into the casing or a cover for the mobile phone.

An emitter of a Ga liquid metal ion source is constituted to include W12 of a base material and Ga9 of an ion source element covering a surface as construction materials. By making back-sputtered particles become elements (W and Ga) of the Ga liquid metal ion sour source, if back-sputtered particles attach to the Ga liquid metal ion source, contamination which may change physical characteristics of Ga9 does not occur. A W aperture is used as a beam limiting (GUN) aperture to place Ga of approx. 25 mg (of melting point of 30° C.) on a surface of a portion included in a beam emission region (Ga store). When emitting ions to the beam limiting (GUN) aperture, Ga in the emission region melts and diffuses on a surface of the beam emission region of the W aperture.
