TechOn reports that Nintendo has been evaluating three-axis acceleration sensor samples from new suppliers that will be used in Wii controllers.
Sources say that Nintendo have been particularly interested in an acceleration sensor from Kionix as it makes it easier to enhance sensitivity.
To quote: Nintendo has been evaluating samples obtained from a number of acceleration sensor manufacturers other than ST and ADI, according to sources. Kionix Inc, a US-based venture firm, once attracted attention as a strong candidate.
Kionix was regarded as such because of the high reliability based on its past records of supplying sensors for hard disk devices, according to a source involved in the case. Also, Kionix's device has a structure different from its competitors: Its MEMS sensor is several times thicker than ADI's device, making it "easier to enhance sensitivity," according to engineers in the MEMS industry.
Nevertheless, Nintendo has not yet decided to change suppliers. Acceleration sensor manufacturers have to satisfy strict specification requirements in order to obtain a contract.
