Patent number: 8833165Abstract: The miniaturized piezoelectric accelerometer includes a support frame (102) having a cavity (104) and a seismic mass (108) supported by a plurality of suspension beams (110) extending from the support frame (102). Each of the suspension beams (110) has a piezoelectric thin film coated on a top surface thereof, with a pair of inter-digital electrodes (114) deposited on an upper surface of each piezoelectric thin film. The presence of acceleration excites bending and thus strain in the piezoelectric thin film, which in turn causes electrical signals to be generated over terminals of the electrodes (114). To collect constructively the output of the electrodes (114), one terminal of each of the electrodes (114) is routed to and electrically connected at a top surface (308) of the seismic mass (108).Type: GrantFiled: September 4, 2009Date of Patent: September 16, 2014Assignee: Agency for Science, Technology and ResearchInventors: Kui Yao, Saravanan Shanmugavel, Trung Dung Luong, Ajit S.

Patent number: 7849896Abstract: An alignment tool for a bonding apparatus comprises a loading surface for receiving a pushing force from a surface of a device which is attached to the bonding apparatus, the loading surface being arranged and constructed to experience a tilting moment upon receiving an unequally distributed pushing force from a misaligned device acting on it. The loading surface transmits the tilting moment experienced by it to a sensing surface which is operatively connected to the loading surface through a columnar body, which has a smaller width than the loading surface and the sensing surface, and which connects the loading surface and the sensing surface. An array of piezoelectric elements communicates with the sensing surface and produces electrical signals in response to the tilting moment such that a computing unit operatively connected to the piezoelectric elements may detect a direction of tilt of the loading surface from the electrical signals produced by the piezoelectric elements.Type: GrantFiled: February 26, 2008Date of Patent: December 14, 2010Assignee: ASM Assembly Automation LtdInventors: Ping Kong Joseph Choy, Chung Sheung Tate Yung, Ju Fan, Hon Yu Peter Ng
