Sigurd Wagner, James C. Sturm, Naveen Verma Princeton University, Princeton, NJ *Equally-Credited Authors (ECAs) Tactile sensing has wide-ranging applications, from intelligent surfaces to advanced robotics. Large-Area Electronics (LAE), based on low-temp. fabrication (<200°C) of thin films, presents distinct capabilities, due to compatibility with a broad range of materials (enabling diverse transducers), as well as large and flexible substrates and materials-deposition methods (enabling expansive and formfitting sensing arrays). However, low performance/energy-efficiency of LAE thin-film transistors (TFTs) necessitates hybrid systems, integrating Si-CMOS ICs for system functions (sensor readout/control, processing, etc.). Initial work shows that a primary challenge in hybrid systems is the large number of interfaces required between LAE and CMOS, particularly as the number of sensors scales [1,2]. This paper presents a force-sensing system that exploits signal sparsity
