Amplitude nonlinearity is found in sensor conductance, and a characteristic equation is formulated for modeling its response under DC-driving voltages below 1 V. The feasibility of such equation is tested on four FlexiForce model A201-100 piezoresistive sensors by varying the sourcing voltage and the applied forces. Since the characteristic equation proves to be valid, a method is presented for obtaining a specific sensitivity in sensor response by calculating the appropriate sourcing voltage and feedback resistor in the driving circuit; this provides plug-and-play capabilities to the device and reduces the start-up time of new applications where piezoresistive devices are to be used. Finally, a method for bypassing the amplitude nonlinearity is presented with the aim of reading sensor capacitance.<\/jats:p>","DOI":"10.3390\/s110908836","type":"journal-article","created":{"date-parts":[[2011,9,15]],"date-time":"2011-09-15T16:44:05Z","timestamp":1316105045000},"page":"8836-8854","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Detailed Study of Amplitude Nonlinearity in Piezoresistive Force Sensors"],"prefix":"10.3390","volume":"11","author":[{"given":"Leonel","family":"Paredes-Madrid","sequence":"first","affiliation":[{"name":"Centre for Automation and Robotics, UPM-CSIC, Ctra.
