Intra body communication technology allows the fabrication of compact implantable biomedical sensors compared with RF wireless technology. In this paper, we report the fabrication of an implantable image sensor of 625 µm width and 830 µm length and the demonstration of wireless image-data transmission through a brain tissue of a living mouse. The sensor was designed to transmit output signals of pixel values by pulse width modulation (PWM). The PWM signals from the sensor transmitted through a brain tissue were detected by a receiver electrode. Wireless data transmission of a two-dimensional image was successfully demonstrated in a living mouse brain. The technique reported here is expected to provide useful methods of data transmission using micro sized implantable biomedical sensors.

“…In IMDs such as cochlear implants and visual prostheses, because of the need for the continuous transfer of high-rate stimulation data to the implant part, employing a highly datarate-efficient demodulator is of key importance [7]. The PSK approach is generally preferred in high-rate data transfer scenarios over its FSK counterpart because of its potential to handle slightly higher bit rates [4].…”

A novel ultra-low power non-coherent BPSK demodulator for biomedical implants is presented. The proposed demodulation technique is based on utilizing a delayed and digitized form of the input signal for the detection of the received data and also for retrieving a synchronized clock signal. The BPSK demodulator circuit proposed in this work is capable of operating at a carrier frequency of 10 MHz with a data-rateto-carrier-frequency (DRCF) of up to 100%. Designed and simulated in a 0.18-µm standard N-Well CMOS technology, the circuit consumes 27.2µW@1.8V. The proposed demodulation concept was also realized on a proof-of-concept prototype circuit board.

Nowadays inductive powering has become a widely spread technique in existing and emerging implanted medical devices (IMD). The geometry of coils couple plays a key role in the design, optimization and evaluation of a biomedical inductive powering unit (IPU). We have proposed a relatively fast method for an execution of these procedures, which is based on a mutual induction calculation using GPU parallel computing. Generally, our approach is to calculate mutual inductance as a function of uncontrolled (axial distance, lateral distance, inclination) and controlled (coils radii, turns numbers, distance between turns) geometric parameters of a coil couple. Calculated geometric functions in its turn are used in the design and optimization procedure to evaluate an IPU performance (e.g., load power). Achieved time gain of the GPU calculations in comparison with the host CPU computing is up to 80 for sequential summation and up to 8 for parallel computing. Also, it is shown that precision of our method is comparable to the precision of existing electromagnetic field solvers, and at the same time, computation time is substantially less (time gain is about 7 . . . 8 for 2D case and about 100 and higher for 3D case). Additionally, we have verified our method experimentally and shown that results of the calculations are accurate enough to predict real IPU performance. Finally, we have given an example of an IPU design optimization using geometric functions calculated with the help of the proposed method.
