Abstract
A structure for pyroelectric IR heat-sensing elements having a wide angle field of view is made by forming the essential heat-sensing elements and the related electronic elements into a planarized-packing configuration suitable for surface bonding. The heat-sensing elements are caused to be inclined and facing each other in a suspended structure so as to increase the sensing viewing angle.
