Basnayake, BADJCK; Amarasinghe, YWR; Attalage, RA; Udayanga, TDI; Jayasekara, AGBP
This paper presents the design and implementation details of an Artificial Intelligent based smart building automation controller (AIBSBAC). It has the capability to perform intelligently adaptive to user preferences, which are focused on improved user comfort, safety and enhanced energy performance. The design of AIBSBAC consists of subsystems of smart user identification, internal and external environment observation subsystems, an artificial intelligent decision making subsystem and also a universal infrared communication system. Furthermore, the design architecture of AIBSBAC facilitates quick install flexible plug and play concept for most of the residential and buildings automation applications without a barrier to infrastructure modifications in installation.

Design and simulation of mems based 5-dof tactile force sensor
(IEEE, 2016-04) Udayanga, TDI; Jayathilaka, WADM; Amarasinghe, YWR; Dao, DV; Jayasekara, AGBP; Bandara, HMND; Amarasinghe, YWR
This paper describes design and simulation of five degrees of freedom (5-DOF) Micro-Electro-Mechanical systems (MEMS) based tactile force sensor. Tactile sensing involves with measuring physical parameters such as force, temperature, etc. with the aid of physical touch. Over the past decades tactile sensors are gaining popularity over non-contact sensors in biomedical and robotic applications. Proposed sensor design with 3mm x 3mm x 300μm dimensions, has the capability to measure not only the magnitude but also the direction of the force applied. A wagon wheel spring structure was proposed, where 8 beams work as springs to relief the force applied. Behavior of these 8 beams are monitored under each loading conditions using defused piezoresistive sensing elements. A finite element analysis of structure was performed to optimize and validate the structure and Multiphysics analysis was performed to validate the working principal of the proposed sensor.

Development of a quantum tunneling composite based 1-DOF tactile sensor
Udayanga, TDI; Fernando, DAMR; Chaturanga, HLPL; Amarasinghe, YWR; Dao, DV
Tactile Sensing is the measure of tactile parameters such as pressure, force, temperature, vibration, etc. by sense of touch. This paper presents the development of a novel one degree of Freedom (DOF) tactile sensor which can be used to measure the force applied at one direction. A novel composite material named as Quantum Tunneling Composite (QTCTM) is used as the sensing element for the developed sensor. The sensor structure consists of a spring load mechanism to increase the sensing range of the QTCTM. Thanks to the improved characteristics and cost effectiveness the sensor application in industry is promising.
