“…When the IEPE is working, an external power supply is required to provide energy for the sensor’s internal signal processing circuit. In recent years, some studies have used the PE for self-generated 3D acceleration, and only a few studies have used the PE as the power source for a 3D acceleration sensor [ 110 ]. Hence, the processing of the PE acceleration sensor’s output signal should be further investigated [ 111 , 112 ].…”

Sensors are an important part of the organization required for robots to perceive the external environment. Self-powered sensors can be used to implement energy-saving strategies in robots and reduce their power consumption, owing to their low-power consumption characteristics. The triboelectric nanogenerator (TENG) and piezoelectric transducer (PE) are important implementations of self-powered sensors. Hybrid sensors combine the advantages of the PE and TENG to achieve higher sensitivity, wider measurement range, and better output characteristics. This paper summarizes the principles and research status of pressure sensors, displacement sensors, and three-dimensional (3D) acceleration sensors based on the self-powered TENG, PE, and hybrid sensors. Additionally, the basic working principles of the PE and TENG are introduced, and the challenges and problems in the development of PE, TENG, and hybrid sensors in the robotics field are discussed with regard to the principles of the self-powered pressure sensors, displacement sensors, and 3D acceleration sensors applied to robots.

“…Since the accelerometer has a little temperature hysteresis, it turns to be a great device for monitoring structures that suffer from significant temperature variation, as, for example, structures located in sites subjected to snow weather or in desert-like places. For more applications, in [86] two-axis MEMS-based accelerometers were used for near-surface monitoring of geotechnical systems, in [87] a self-power vibration measurement system is proposed which is based on a piezoelectric material which harvests the energy from ambient vibration source and transforms into useful electrical output power of a ADXL-335 accelerometer, in [88] a wireless and battery-free passive sensing platform is proposed for structural damage detection; in [89]…”

In this paper, the use of MEMS accelerometers for measuring mechanical vibrations is presented. Also a wide review of the literature is performed by presenting the uses of the MEMS accelerometers in a great number of applications. These sensors are known for their low prices, low power consumption and low sizes, which enhance their use in applications such as energy harvesters, monitoring processes and for educational purposes. In order to propose these sensors for measuring vibrations, a complete evaluation of the MEMS accelerometers was performed by measuring amplitudes and frequencies of oscillations and comparing their dynamic characteristics with other accelerometers with higher precision. Moreover, two experiments were conducted: In the first one, the measurements of the amplitude given by a MEMS and a standard accelerometer while being excited with sinusoidal waves with different frequencies using a vibration exciter were taken and compared. For the second experiment, three MEMS sensors and a piezoelectric accelerometer were used to measure the accelerations of a 3-DOF shear-building excited by an unbalanced DC motor. The signals obtained were compared in the time and frequency domains; for the last case, the wavelet transform, the wavelet coherence and the power spectrum density were used.
