Home Projects Telehealth Innovation – Connecting Patients to their Carers

The Challenge

Changing demographics and an ageing population is putting an increasing burden on the NHS, risking its ability to provide care free at the point of access.

Does technology have a solution to this problem? Can management of health be transformed by widespread deployment of low cost integrated medical devices capable of collecting basic patient physiological data and transferring it to cloud-based centres for analysis?

MonitorMe was conceived as a novel vital-signs monitoring telephone, simple to use but capable of providing rich information to healthcare providers and carers.

The Approach​

The telephone handset is equipped with sensors to capture vital physiological signs and send them via telephone lines to a digital patient record, which could be analysed by a medical professional if significant changes were identified.

Plextek scientists thoroughly investigated the system requirements and created a whole-system simulation to understand the limitations of the system and test our intended solution.

We worked closely with the company throughout the development process, integrating four vital-signs sensors into a robust telehealth device capable of providing accurate information to a back-end patient database.

The Outcome

The delivered MonitorMe phone fully supported full-duplex DTMF signalling to a local telehealth server emulator. In order to interface with the public network the existing DTMF tones were matched to the connected network characteristics to protect the phone and user.

The Plextek team developed and delivered a solution that utilised appropriate design principles to allow eventual CE certification of the final product.

Completion of the development programme for this advanced prototype enabled our client to begin usability trials with hospitals in Leeds and Newcastle in order to acquire a CE mark and bring the product to market.

mmWave Imaging Radar

Camera systems are in widespread use as sensors that provide information about the surrounding environment. But this can struggle with image interpretation in complex scenarios. In contrast, mmWave radar technology offers a more straightforward view of the geometry and motion of objects, making it valuable for applications like autonomous vehicles, where radar aids in mapping surroundings and detecting obstacles. Radar’s ability to provide direct 3D location data and motion detection through Doppler effects is advantageous, though traditionally expensive and bulky. Advances in SiGe device integration are producing more compact and cost-effective radar solutions. Plextek aims to develop mm-wave radar prototypes that balance cost, size, weight, power, and real-time data processing for diverse applications, including autonomous vehicles, human-computer interfaces, transport systems, and building security.

On the Radiation Resistance of Folded Antennas

This technical paper highlights the ambiguity in the antenna technical literature regarding the radiation resistance of folded antennas, such as the half-wave folded dipole (or quarter-wave folded monopole), electrically small self-resonant folded antennas and multiple-tuned antennas. The feed-point impedance of a folded antenna is increased over that of a single-element antenna but does this increase equate to an increase in the antenna’s radiation resistance or does the radiation resistance remain effectively the same and the increase in feed-point impedance is due to transformer action? Through theoretical analysis and numerical simulations, this study shows that the radiation resistance of a folded antenna is effectively the same as its single-element counterpart. This technical paper serves as an important point of clarification in the field of folded antennas. It also showcases Plextek's expertise in antenna theory and technologies. Practitioners in the antenna design field will find valuable information in this paper, contributing to a deeper understanding of folded antennas.

Frequency-Scanning Substrate-Integrated-Waveguide Meanderline Antenna for Radar Applications at 60GHz

This paper describes the design and characterization of a frequency-scanning meanderline antenna for operation at 60 GHz. The design incorporates SIW techniques and slot radiating elements. The amplitude profile across the antenna aperture has been weighted to reduce sidelobe levels, which makes the design attractive for radar applications. Measured performance agrees with simulations, and the achieved beam profile and sidelobe levels are better than previously documented frequency-scanning designs at V and W bands.

A Ku-Band, Low Sidelobe Waveguide Array Employing Radiating T Junctions

The design of a 16-element waveguide array employing radiating T-junctions that operates in the Ku band is described. Amplitude weighting results in low elevation sidelobe levels, while impedance matching provides a satisfactory VSWR, that are both achieved over a wide bandwidth (15.7-17.2 GHz). Simulation and measurement results, that agree very well, are presented. The design forms part of a 16 x 40 element waveguide array that achieves high gain and narrow beamwidths for use in an electronic-scanning radar system.

Sensing Auditory Evoked Potentials with Non-Invasive Electrodes and Low-Cost Headphones

This paper presents a sensor for measuring auditory brainstem responses to help diagnose hearing problems away from specialist clinical settings using non-invasive electrodes and commercially available headphones. The challenge of reliably measuring low level electronic signals in the presence of significant noise is addressed via a precision analog processing circuit which includes a novel impedance measurement approach to verify good electrode contact. Results are presented showing that the new sensor was able to reliably sense auditory brainstem responses using noninvasive electrodes, even at lower stimuli levels.

Long Range Retro-Reflector

Passive retro-reflectors that modulate a scattered RF signal but do not transmit in their own right are well known. They are widely used in RFID tags, and keyless entry systems with a number of standardised solutions defined within the industry. The main advantage of these systems is that the mobile unit (the tag) can either avoid completely the use of a battery by powering itself from the incident RF ‘interrogating’ signal or only require a very small battery with a long life. This enables a ‘disposable’ tag to be engineered at very low cost, size and weight. However, there are many potential applications that require a somewhat longer transmission range than can sensibly be achieved with this method. The conventional paradigm requires a higher power ‘interrogating’ signal in order to increase range and there are obvious limits to how far this can be taken. The combination of regulatory restrictions and the steep range vs power slope that results from the fundamental mode of operation generally restrict the range to a few metres at most. Plextek have been taking a fresh look at the possible ways of circumventing this obstacle to produce a long range device that is nevertheless RF passive (does not transmit but only scatters). This paper describes in outline some ideas in this space, some initial experiments that have been done and some potential applications of the techniques.

An Optical Room Occupancy Sensor

An automated sensor system that determines whether rooms within a building are occupied by a person or people has many applications. These divide broadly into the following classes: Security: Whole-site surveillance from control node, cases where a room should not be occupied, intruder detection and asset tracking. Safety: Identification of lone workers during non-core hours and remote supervision of isolated working environments. Confirmation of building evacuation. Management of high risk processes. Facilities Management: Environmental controls (lighting/heating) to meeting room booking aid. Sensors that seem to solve this problem are plentiful and it is only when they are considered in detail that their deficiencies become apparent. This short paper makes this case and introduces a new type of sensor based on an optical method.
