“…Exploring home appliances further, there are many potential areas in which home appliances can be improved by adding new features, applications, and extensions [20]. In the example of washing machines, IoT extensions can be used to detect the vacancy state [16] of the machine, and to report back to registered users in a shared user setting. For traditional home appliances, the control of the unit is usually done from the embedded microcontroller in the appliance.…”

Due to increasing urbanization in Bangkok, Thailand, it is observed that there are an increasing number of people who have moved into high-density apartment/condominium complexes. One common service that is provided at such complexes is the provision of public coin operated washing machines that allow tenants to do their laundry at a reasonable price. This has led to a new set of challenges, one of which is that the number of public coin operated washing machines is usually inadequate during peak hours, leading to long waits in queues for the tenants. The development of smart public coin operated washing machines has improved the quality of life of the tenants. This research proposes a smart public coin operated washing machine platform by extending the usefulness and convenience of existing washing machines using IoT applications. The infrastructure, the proposed application features, and the vacancy state detection of the new washing machine platform are discussed. Using the proposed platform, tenants using public coin operated washing machines can better plan when to do their laundry even during peak hours, improving their quality of life.

“…In future smart cities, most domestic devices will be connected to internet of things (IoT) to improve their performance and communication with users and other devices. IoT can include everyday objects, such as laptops, mobile phones, washing machines, air conditioners, wearable devices, refrigerators, and other electronic devices [1][2][3][4]. IoT will allow a network between these devices for their remote distance control.…”

Microelectromechanical system (MEMS)-based piezoelectric energy harvesting (PEH) devices can convert the mechanical vibrations of their surrounding environment into electrical energy for low-power sensors. This electrical energy is amplified when the operation resonant frequency of the PEH device matches with the vibration frequency of its surrounding environment. We present the electromechanical modeling of two MEMS-based PEH devices to transform the mechanical vibrations of domestic washing machines into electrical energy. These devices have resonant structures with a T shape, which are formed by an array of multilayer beams and a ultraviolet (UV)-resin seismic mass. The first layer is a substrate of polyethylene terephthalate (PET), the second and fourth layers are Al and Pt electrodes, and the third layer is piezoelectric material. Two different types of piezoelectric materials (ZnO and PZT-5A) are considered in the designs of PEH devices. The mechanical behavior of each PEH device is obtained using analytical models based on the Rayleigh–Ritz and Macaulay methods, as well as the Euler–Bernoulli beam theory. In addition, finite element method (FEM) models are developed to predict the electromechanical response of the PEH devices. The results of the mechanical behavior of these devices obtained with the analytical models agree well with those of the FEM models. The PEH devices of ZnO and PZT-5A can generate up to 1.97 and 1.35 µW with voltages of 545.32 and 45.10 mV, and load resistances of 151.12 and 1.5 kΩ, respectively. These PEH devices could supply power to internet of things (IoT) sensors of domestic washing machines.
