\caption[vibrotactile circuit and signal.]{On the left: electrical diagram for driving the actuators. Two signals, one for Frequency and the other for Amplitude are modulated. On the right: a low-frequency signal with 50\% duty cycle for Frequency, a high-frequency signal with an adjustable duty cycle for Amplitude, and the modulation of both signals.}
