Numerous investigations and academic studies employ piezoresistive types of sensors. One of the main foundations of this thesis is to contribute to the literature by making a detailed error analysis and by proposing a new error reduction. In this thesis, piezoresistive touch sensors are designed and manufactured from scratch in accordance with the working principle of commercially available sensors. This thesis examines two different sensor configurations for single-touch applications. On these sensors, three different loads are tested statically with the same 61 test points located on the sensor, a single load at a time, and their Center of Pressure results are examined and compared to each other. As a result, it is observed that the 7x7 sensor array gives more successful results than the 5x5 sensor array at the same test points. Kadane's algorithm is introduced and implemented in experiments aimed to reduce the error values. As a result, success is achieved. Furthermore, with another proposed method, circle fitting, the centers of the theoretical circle formed by measurements are found, and it is examined whether the sensor measurements were considered as homogeneous. In other words, in each case, the levels of decentralization did not vary much. Finally, the multivariate linear regression method is examined through the system equations obtained from the randomly selected measurement points. It is seen that both the sensor outputs of the other points on the system can be predicted and the error metrics on the system can be reduced.

520 $a Cok sayida arastirma ve akademik calisma, piezorezistif sensor turlerini icermektedir. Bu tezin temel dayanaklarindan biri, detayli bir hata analizi yaparak ve yeni bir hata azaltma onerisinde bulunarak literature katkida bulunmaktir. Bu tezde, piezorezistif dokunmatik sensorler, piyasada bulunan sensorlerin calisma prensibine uygun olarak sifirdan tasarlanmis ve uretilmistir. Bu tez, tek dokunuslu uygulamalar icin iki farkli sensor konfigurasyonunu incelemektedir. Bu sensorlerde, sensor uzerinde bulunan ayni 61 test noktasi, bir seferde tek bir yuk olmak uzere toplamda uc farkli yuk altinda statik olarak test edilmis, bu noktalarin basinc merkezi sonuclari incelenmis ve birbirleriyle karsilastirilmistir. Sonuc olarak 7x7 sensor dizisinin ayni test noktalarinda 5x5 sensor dizisinden daha basarili sonuclar verdigi gozlemlenmektedir. Kadane algoritmasi, sensorlerdeki hata degerlerini azaltma amaciyla deney verilerine uygulanmistir. Sonuc olarak, basari elde edilmistir ve hatalarin azaldigi gozlemlenmistir. Ayrica onerilen bir baska yontem olan daire uydurma ile olcumlerle olusan teorik cemberin merkezleri bulunarak sensor olcumlerinin homojen olarak kabul edilip edilmedigi incelenir. Baska bir deyisle, her durumda, merkezden kaciklik seviyelerinin cok fazla degismedigi deneyimlenmistir. Son olarak, rastgele secilen olcum noktalarindan elde edilen sistem denklemleri uzerinden cok degiskenli dogrusal regresyon yontemi incelenmistir. Hem sistem uzerindeki diger noktalarin sensor cikislarinin tahmin edilebildigi hem de sistem uzerindeki hata metriklerinin azaltilabildigi gorulmektedir.
