Tim Moutafis – Engineer / Inventor

SensorCells, the technology at the core of a transformative therapeutic surface, were invented by  Tim Moutafis and perfected with the aid of the University of Massachusetts – Lowell plastics engineering group.

Tim formed TheraTorr Medical, Inc. and created a full-sized functional therapeutic surface using over 500 independent SensorCells to support a patient’s body.  The full-size prototype was used to perform extensive data collection and competitive comparative testing to validate the technology and the concept. Since each column can yield up to 6-inches, the body can sink into the surface like sinking into a deep pillow. Deeper immersion into the surface means that more of the patient’s body surface will bare the patient’s total weight, reducing the contact pressure on each and every body part.  Comparing our surface immersion depth to therapeutic surfaces currently available, our surface has twice the immersion depth, which allowed more surface area to bare the total weigh of the patient.  The results of our laboratory testing…we reduced dangerous tissue interface pressure by 40% over the best that the market has to offer!  


The SensorCell is based on a simple mechanical device known as a rolling diaphragm.  It is the basis of a totally new therapeutic bed concept that is disruptive and will transform the environment for seriously ill patients confined to a bed with burns or serious pressure ulcers.

Unfortunately Mr. Moutafis, beset with health issues, was unable to continue working full-time on his invention.

In 2018, LeviSense Medical acquired all the assets of TheraTorr Medical, including the SensorCell IP to continue this important work.  Mr. Moutafis serves as an advisor to LeviSense.

SensorCell Envelopment

The core concept of SensorCell Flotation Therapy is to create a surface that perfectly conforms to the patient’s anatomy, enveloping even the most aggressive bony protrusion with gentle support.  Our support surface works like the toy called “pin art.”  Like pin art, each SensorCell is displaced by the pressure applied by the body.  The body is immersed and perfectly enveloped by the cavity that is created in the surface.  The amount of resistance to displace by the SensorCell is controlled by the air pressure within the cell, which is exactly the same pressure that the tissue will experience.  The pressure that a surface or mattress exerts on the skin in any area is called the tissue interface pressure or “TIP.”   High TIP for a prolonged period is one of the most serious risk factors for the formation of pressure ulcers.  Pressure mapping is used to measure the patient’s TIP on a support surface.

Our support surface is comprised of hundreds of SensorCells, which react independently to the contours of the patients body and cannot apply more pressure to the skin than the pressure in the cell.  The pressure cannot increase even thought the patient may be deeply immersed in the surface.  The deeper the patient sinks into the surface, the more surface area is used to support the patient’s weight.  The result is stable and restful therapeutic surface that protects the tissue from excessive pressure, even on the bony protrusions.



Active Sensing and Control

The SensorCell and Sealed Sensor Cluster

LeviSense has developed an advanced sensor technology and endowed each cell with a sensor array that can detect and monitor the height and pressure within the cell.  The sensor cluster is encapsulated and sealed in each cell and allows the system to monitor the tissue interface pressure of each cell.  The data can be stored on-board the system, viewed at bedside or transmitted to a caregiver at a remote location.  The result is real-time pressure mapping and monitoring.

Cell height sensing allows the system to observe, monitor and report the patient’s positions and position changes.

The last step was to include an individual air flow control valve in each sealed sensor array.  Now the SensorCell not only reports the height and pressure within each cell, but receives real-time height and pressure regulation from the control software.  Each cell can be programmed, individually for the desired height and pressure.  The result is LeviSense SensorCell Flotation Therapy.

Real-Time Monitoring for Custom Wound Therapy

Dr. Richard Viglione, LeviSense’s clinical advisor says,  “Wound healing is a complex and dynamic process that requires a team effort by the patient, primary care physician and experts in the care and healing of wounds.”  The LeviSense SensorCell Flotation Therapy System is the first and only system that delivers accurate timely information and the ability to adapt the surface to the unique needs of the patient so a wound care team can take effective action to a dynamic situation.
