| 1. A bioinformation detector comprising:
(a) a pedestal including an open-top pedestal cavity;
(b) a diaphragm closing the open top of the pedestal cavity;
(c) a cap mounted on the pedestal, the cap defining a cap cavity open to the diaphragm;
(d) a resilient member installed between the pedestal and the cap for hermetically sealing a joint therebetween when the cap
is loaded with an object for bioinformation detection; and
(e) a strain sensor attached to the diaphragm for sensing changes in air pressure in the hermetically sealed space.
