Some tradeoffs for interfaces to piezoresistive sensor arrays

The author presents a quantitative study of some of the tradeoffs between interface electronics complexity, numerical computational burden, and number of array accesses that exist in the implementation of sensing systems using piezoelectric arrays. For each level, it is shown what information can be obtained, and algorithms are given that extract the stated information from the array. For the most capable interface, tradeoffs between computation and the number of array accesses exist; algorithms that exploit these various tradeoffs are given
