  For getting good sleep quality, an improved approach of new mattress
development based on the pressure sensors for body-contouring uniform support
is proposed in this paper. This method solved the problems of innerspring
mattresses that cannot allow body-contouring uniform support, and foam
mattresses that cannot provide everybody equal comfort from the same mattress.
By the buried pressure sensor array and actuator array in foam layer of a
mattress, both are connected to a controller to generate the pressure
distribution mapping of a human body on the mattress, then from the data of
this mapping, some of the actuators are driven up or down by the controller to
generate a body-contouring uniform support. By the aid of mathematical
morphology algorithms, user can also choose a different support mode by another
wireless controller with touch-screen to accommodate personal favorite firmness
of the mattress and to take his tensed mood and pressure off with good sleep
until daylight. Moreover, some other homecare functions, such as temperature
measurement, sleep on posture correction and fall down prevention, can approach
by additional hardware and software as user requirement in the future.
