From: A spiking and adapting tactile sensor for neuromorphic applications
Proposed circuit as an adapting force sensor with a spike based read out. The circuit can be divided in three functional stages. The first stage is the signal sensing and conversion for the sensation of force at its conversation to a loading current for the second stage. Here, the current is integrated. When a certain voltage is reached the positive feedback loop in the third stage fires. The resulting spikes can be measured as a voltage drop over \(R_{K}\) and further processed.
