A readout circuit for a tactile sensor pad based on force sensing resistors was proposed, which was composed of an analog signal conditioning circuit and a digital circuit with a microcontroller. The conventional signal conditioning circuit has a dc offset voltage inthe output signal, which results from the reference voltage applied to the FSR devices. The offset voltage reduces the dynamic rangeof the circuit and makes it difficult to operate the circuit under a low voltage power supply. In the proposed signal conditioning circuit, the dc offset voltage was removed completely. The microcontroller with A/D converter and D/A converter was used to enlarge the mea- surement range of pressure. For this, the microcontroller adjusts the FSR reference voltage according to the resistance magnitude of FSRunder pressure. The operation of the proposed readout circuit which was connected to a tactile sensor pad with 5 x 10 FSR array wasverified experimentally. The experimental results show the proposed readout circuit has the wider measurement range of pressure than the conventional circuit. The proposed circuit is suitable for low voltage and low power applications.
