Embedded C is a language programming expansion of C programming to address the communication between different embedded systems. A large portion of the syntax and semantics of embedded C, for example, main function, variable, data type, loops, functions, arrays and strings, structures and so on resemble standard C programming. In short, embedded C deals with microcontrollers, input/output ports (RAM, ROM), whereas C deals with only memory and operating systems. C is a desktop programming language used for embedding a piece of software code into the hardware to make it function. Here, the program on the wearable sensor operation was written using embedded C.

The prepared samples were analyzed according to the described procedures.[32] The interdigitated electrode is first immersed into an oil-filled plastic beaker. The leads of the electrodes are connected to the AD5933 board. An Arduino MKR Wi-Fi 1010 microcontroller is used as a master to control and command the AD5933. An embedded C++ program is written to set the amplitude of the sinusoid, initialize the starting frequency, perform the frequency sweep, and record the impedance measurements. The impedance spectrum of a sample is obtained by performing a frequency sweep from 5 to 98 kHz with a step size of 1 kHz. The frequencies which are ≥ 5 kHz and ≤50 kHz are considered to be low frequencies. Frequencies from 50 to 98 kHz are the high frequencies. The absolute complex impedance value is recorded at each excitation frequency.

where a is the radius of the ring, is zero of the derivative of Bessel function, is the velocity of light, fr is the resonating frequency and ɛr is the relative permittivity. After optimisation, the outer radius of the rings is calculated as 16 mm, 13 mm, 10 mm, 7 mm and 3.4 mm (larger to smaller ring) for obtaining the resonating frequency bands. The half ring width L of the three outer rings is considered as 3 mm whereas the width of the fourth ring is optimised as 3.15 mm followed by the fifth ring with thickness 0.8 mm. The radius of the ground embedded C-slot is optimised as 21 mm (Figure 1(b)). The proposed antenna radiator is excited by means of a 50-ohm microstrip line as shown in Figure 1(a). The total size of the antenna is 36.8 × 60 × 1.59 mm3.

This work describes the design of a cost-effect yet versatile stabilisation platform that can assist Parkinson’s disease patients with handling loads that are prone to spillage or breakage. It is comprised of a modular set-up of inertial measurement unit (IMU), microcontroller and servo motors, all three of which can be switched in and out for the parts best suiting a given application. At the heart of the design is the algorithm to be executed on the microcontroller – an embedded C programme that can retrieve data from a position sensor like an IMU and then instruct the motors to move counter to any changes in the sensor’s position. For the purposes of demonstration at this stage, the platform has been incorporated into a tray in which objects can be placed and carried without fear of dropping them. The details of the design of this platform, the design of the tray and the testing of the platform are expounded upon in this article.
