Abstract: A formaldehyde sensor using a piezo-resistive cantilever is provided to predict sick house syndrome in advance by selectively detecting formaldehyde for preparing against the sick house syndrome. A formaldehyde sensor using a piezo-resistive cantilever includes a cantilever(1), a gold coating film(6), and a mercaptophenol. The cantilever is fixed on a measurement chip(2) and includes a piezo-resistive unit(3). A wheatston bridge is embedded in the measurement chip. The piezo-resistive unit is R1 of the wheatston bridge being connected with R2, R3, and R4 through an electrical connector(5), is dopped and inserted in an upper part of a central shaft, and is folded with the cantilever when the cantilever is folded. The gold coating film is formed on an upper surface of the cantilever for sticking the mercaptophenol thereon. The mercaptophenol detects formaldehyde.
